'Battlestar Galactica' alum Katee Sackhoff may be best-known amongst the sci-fi nerd sect, but the charismatic blonde actress has appeared in several prime-time shows and is gearing up to begin a new, big venture on A&E's 'Longmire,' in which she gets top billing.

AOL TV caught up with Sackhoff as she worked the Comic-Con/Fan Expo circuit to promote her voicework in the feature-length animated film, 'Batman: Year One.' We spoke to her about saying goodbye to 'Battlestar' and Starbuck for good, 'Longmire' and why it's so tough in Hollywood these days.

Attention 'Battlestar Galactica' fans: Katee Sackhoff is returning to TV in a series regular role!

According to the Hollywood Reporter, A&E has ordered 10 episodes 'Longmire,' a new series about a widowed sheriff in Wyoming. Sackhoff will play one of his deputies. The series also stars Robert Taylor, Lou DIamond Phillips, Bailey Chase and Cassidy Freeman.

The series is based on Craig Allen Johnson's Walt Longmire series of novels.

Actors can work for years before they get their big break, going from project to project, floundering away on struggling sitcoms and concept-heavy dramas until their luck changes and -- blamo! -- they're on a successful show raking in six figures per episode.

These thespians aren't quite show-killers -- they just have bad luck!

From Bret Harrison to Joanna Garcia and so many more, we're saluting these bad luck stars. Somebody get them a four-leaf clover and a hit show -- stat!

Lady Gaga will kick off the summer concert series on 'Good Morning America.'

ABC announced the news during this morning's 'GMA' broadcast. Look for Gaga to take the stage on May 27, four days after her new album drops.

'GMA' has been beefing up its content to draw younger viewers. Last month the morning show welcomed Britney Spears with a concert event.

Last summer Lady Gaga took the stage as part of the 'Today' show's summer concerts.

Well frak me! 'Battlestar Galactica' veteran Katee Sackhoff is getting around at CBS.

Mo Ryan reported that Sackhoff will return to 'The Big Bang Theory' this season, and now The Ausiello Files is reporting the '24' actress has booked a possible recurring role on 'CSI.'

According to the report, Sackhoff will play Detective Reed, a tough, insensitive and smart investigator. Look for her to pop up during November sweeps.

However, this isn't the first time Sackhoff has been reportedly joining 'CSI.'

I found out that 'The Big Bang Theory' is breaking out the big guns for its impending move to Thursdays, and I just had to get this exclusive news out there now: Katee Sackhoff is guest starring on the CBS comedy again this fall.

The actress, who played Kara "Starbuck" Thrace on 'Battlestar Galactica' and Dana Walsh on '24,' won't be in the season premiere of 'Big Bang' (Thurs., Sept. 23, 8PM ET on CBS), but keep reading for scoop on that one, too.

How far is too far, if you're a special agent? On '24' (Mon., 9PM ET on Fox), Jack Bauer (Kiefer Sutherland) goes all out to catch a killer -- and to avenge the death of a loved one. Does his quest for vengeance get the better of him?

[Spoiler alert.]

Jane here, filling in for Mike. I was actually reviewing '24' at the beginning of the season, but found the storyline so preposterous that Mike graciously agreed to take it off my hands.

Somewhere between then and now, the show has gotten much better -- more interesting and less ridiculous. In fact, last week, my nephew emailed me and said the show's gotten better lately, especially with the return of Charles Logan. I wholeheartedly agree. Not that Logan's any less of a weasel, but that's what I love about him.

The clock is ticking down on '24' (Mon., 9PM ET on Fox) as the show nears the end of its final season. The pressure is intensifying. Now, everyone is after Jack Bauer (Kiefer Sutherland) -- even members of his own team.

Watch the video after the jump.

(S08E16) The second hour of Fox's '24' double-bill kicked off with the hunt for the CTU mole. This was probably the stronger episode of the two that aired last night, considering the shocking development that ended the hour. This season still feels like its rehashing old plots and twists, but a few of tonight's scenes and images will probably be burned into the memories of fans for some time to come.

Head after the jump for the spoils.

(S08E15) The sun finally came up over Jack Bauer and crew last night on '24'. And with it came the first of two exciting if ultimately empty-feeling hours of the veteran real-time drama.

I use the word empty to describe these episodes because I'm no longer very invested in the story. '24' lost me a few weeks ago, even before Dana so inelegantly stuffed Stephen Root's dead body behind a CTU wall panel. Like I typed last week, the twists feel cheap, the stakes arbitrary, and the real-time gimmick has gotten stale.

At this point I'm mostly watching for the tightly edited procedural elements, the action scenes, and Kiefer Sutherland's sturdy performance. That stuff is solid -- so solid that it almost makes up for the lack of compelling drama and the unbelievable plot developments this season.

Head after the jump for spoilers, and remember to check out our recap of the next hour when it goes live.

(S08E14) Judging by tonight's ep, it looks like we can expect more lunacy and lazy story developments as '24' heads into its final hours. It's probably best for the show to end its run after this season. At this point, '24' is merely recycling its once startling twists and turns, and the real-time gimmick has gotten stale. We have a new locale and a few new names and faces, but the tricks are all the same, and the suspense feels manufactured, cheap and forced. Fans can see the twists coming from hours away, even when they're as unbelievable and over the top as they have been this year.

Jack Bauer is long overdue for a trip to the big screen. Hopefully, the tired real-time dramatic device that has outworn its welcome on TV won't shackle the character once he jumps to the movies. I'd much rather see Kiefer battling the baddies in a dense, smartly paced thriller than sit through another ridiculous real-time setup.
