Marg Helgenberger, the actress who plays forensic scientist Catherine Willows on 'CSI', told TV Squad today that her contract on the show is up after 10 years and that she hasn't yet been asked back for next season.

"My contract is up actually," Helgenberger said, when asked if she would be returning for 'CSI's' 11th season. "That's a good question. I haven't been asked back, so we'll see."

Fans of the original 'CSI' can try their hand at solving a murder right in the middle of the massive MGM Grand Las Vegas.

'CSI: The Experience' offers visitors families (and other visitors looking to escape the constant "dinging" and "blooping" of slot machines) a chance to follow a simulated murder case from the initial crime scene to a selection of the most likely suspect.

While the attraction's designers struggled in vain to make it a compelling and vibrant way to kill an hour or so, the exhibit is essentially a course in basic forensic science and observation.

On a recent trip to Vegas and the MGM on business, I decided to scoop up my magnifying glass (which I always take with me on vacation) and give it a try.

Michael is scheduled to return to one of the realities of 'Lost' this season, but that's not the only place we can expect to see Harold Perrineau this spring. According to Entertainment Weekly, Perrineau is schedule to guest star on an April episode of 'CSI: NY.' He'll be playing the role of a death row inmate who must fight for his life during a prison riot.

The part that gets interesting for fans of the crime procedural is that Sheldon Hawkes will be in the prison along with Perrineau's character. What he's doing there hasn't been revealed, but there's apparently a connection between his past and Perrineau. I thought it might have more to do with his recent financial troubles, but perhaps there are secrets in Hawkes' past that will make his recent troubles seem like child's play.

A lot has been written about the rather............dramatic...........way David Caruso talks on CSI: Miami. Now CBS wants you to show them your best Horatio Caine impression! Just upload a video of yourself by February 22 and you could win $5000!

If you need a pointer or two, here's Jim Carrey's take.

Good news for Patrick Warburton fans; disappointing news for Jenna Elfman fans. And if you have a deep affection for Jeremy Northam, this should make you happy, too. Confused? Don't be. I'm just laying out the essence of the CBS midseason juggle.

On Mondays, beginning February 1, Accidentally on Purpose will be shelved... but only for a few weeks. Taking the 8:30 Monday slot will be the return of Patrick Warburton, the best thing in Rules of Engagement.

That's not all. On March 31, the 8:30 slot in which Gary Unmarried airs, will be assumed by Accidentally. That's not because Gary's being canceled; it will have completed its season order by then.

Have you received all your Christmas gifts? Would you like one more? Okay, here it is, when Burn Notice returns for the winter season on January 21, the first episode will include guest star Tyne Daly. That's right, Tyne will be reuniting with her Cagney & Lacey co-star Sharon Gless. This is will be the first of seven new Burn Notices till next summer.

There's another Cagney & Lacey story in the news. CSI creator Anthony Zuiker wants to revive the show for CBS. For those who don't recall, Cagney & Lacey was the top female cop drama of the 1980's -- actually of all time. It was a serious police drama, unlike something jiggly like Charlie's Angels or safe and pedestrian like Police Woman.

One of the most coveted parcels in prime time real estate is the hour after the broadcast of the Super Bowl. In 2010, CBS has the big game on Sunday, February 7, and after the pads pop and the Vince Lombardi trophy is hoisted, the program that the Tiffany network will air is not one of the usual suspects. The slot won't be used to pump up the next edition of Survivor, as many experts guessed.

It also won't be used to reinforce the success of sophomore drama The Mentalist, nor will the space be handed over to The Big Bang Theory for a one-hour stretched out sitcom episode. And the network isn't going to pump up a slipping series like CSI, which isn't getting the gaudy numbers it did in the William Peterson days. So, what will they run? Follow me after the jump to find out -- and consider this a SPOILER ALERT.

Remember those pop-up books you used to read as a kid and the sheer fun you had make the bunny jump over the fence or the kid deliver jelly beans to the sausage factory?

Why can't adults have the same thing? And I mean for books other than dirty ones?

Quirk Books and Chronicle Books have done just that with the never-ending CSI franchise. CSI: The Interactive Mystery by Sam Stall is a hardcover short mystery story done in the traditional style but with an interesting twist that makes it a fun and unique read. And yes, it still requires reading. Screw Egon Spengler, print ain't dead.

Welcome to our new feature, TV Squad readers. How well do you know what you think you know about television? Play our little trivia game, Fact or Fiction. We'll state the premise, then tell you the reality, i.e. the fact or the fiction. By the way, if you have ideas for Fact or Fiction, or questions you'd like us to figure out, share with us in the comments.

Fact or Fiction: When Chuck Lorre originally created The Big Bang Theory, the boys were dominated by a nasty neighbor named Katie.

Fact! Chuck Lorre told Watch magazine's Jim Colluci that a year before The Big Bang Theory was picked up by CBS, the first pilot had a female character named Katie. She manipulated the guys. "It was like shooting fish in a barrel. It didn't work," Johnny Galecki told Colluci. The problem was that Sheldon, Leonard, Raj and Howard were and are essentially innocents and without maliciousness. The idea of a woman taking advantage of their innocence was not only mean, it wasn't funny. The writers went back to the drawing board -- so to speak -- and, thus, the character of sweet, gentle Penny was born.

Three episodes into CSI's tenth season and it turns out that Jorja Fox's five episode return to the show has been extended "indefinitely." According to TVGuide.com, executive producer Carol Mendelsohn has confirmed that Fox's Sara Grissom will be around for many more episodes this season than originally planned.

Thus far, Fox has appeared in the first two eps this season. So there's still three left in her original contract and while it's still unknown how many more episodes she'll be in, you can probably figure on at least half the season.

That can't bode well for Sara and Gil fans. Grissom had a tough time last season without Sara around and I have a hard time believing that they'll be able to sell us a happy relationship between the two of them with Sara in Las Vegas and Gil traveling the world to give lectures.

Generally speaking, the CSI franchise has been a ratings juggernaut for CBS. Still, this season the original CSI has been declining a bit. It started last season when Laurence Fishburne took on the role of Dr. Ray Langston, becoming the main man on the show with William Petersen exiting.

Well, in an effort to perhaps pump up Fishburne's popularity, CBS is doing something unique. For the first time, a CSI character -- Langston -- will crossover to the other two shows in the same week, all part of the same story.

Will it work? Probably. Crossover stunts are always fun and it'll give viewers who watch one of the CSI's or two, to sample the other. That's not as weird as it sounds. I only watch CSI, not NY or Miami.

Stealing scenes on the small screen is nothing new for Christian Slater. The actor, known for films like Heathers, True Romance and Pump up the Volume, has made memorable guest appearances on shows like Alias, The West Wing and My Name is Earl. His first shot at his own series, the NBC spy thriller My Own Worst Enemy, struggled to find an audience, leading the network to cancel it halfway through the first season.

Slater is back starring in a new series, The Forgotten, produced by CSI head honcho Jerry Bruckheimer. The ABC procedural follows a team of amateur detectives who work murder cases involving unidentified victims, or John and Jane Does. Slater plays former cop Alex Donovan, whose search for his missing daughter inspires him in the field.

I got the chance to talk with Slater about The Forgotten, his new career in TV, and what one of his most famous big screen characters would think about his latest role.

One of the most talked-about aspects of CSI: Miami is the fact that David Caruso wears sunglasses a lot and whips them off and says dramatic things. It has even been parodied by everyone from Jim Carrey to YouTube members.

This clip below is a behind the scenes look at the season premiere of the show, where we find out how Horatio's team was put together and how Horatio got those sunglasses.

What will happen to CSI: Miami's Eric Delko (Adam Rodriguez)? That's one of the questions that the September 21 season premiere will answer. Here's a sneak peek of the episode. He isn't looking too good here, but remember: Dr. Drake Ramoray fell down an elevator shaft, smashed his brain and died and he came back good as new.

A good show can keep you so entertained that you're willing to fight sleep to watch the rest of it. A great show physically keeps you awake.

It gets into your bloodstream and forces more adrenaline into your heart.

It turns the synapses in your brain into ferrets on espresso that dash back and forth between the lobes and fires your mind on all of its cylinders.

It is visual cocaine, which is much healthier than actual cocaine and doesn't require a frequent visitor punch card for an eyes, ears, nose and throat doctor.

These are the shows that assault all five of the senses or less depending on how good of a health plan you've got.
