Adrian Pasdar and Michael Imperioli have joined the cast of Doug Ellin's '40.'

The comedy about middle-aged men also stars Ed Burns and Michael Rapaport.

The single-camera comedy follows four lifelong friends as they navigate their 40s. Burns plays a married man and father who used to well-off, but hasn't worked in almost a year. According to Deadline, Rapaport's character is a married "neurotic everyman." 'Sopranos' veteran Imperioli plays a single man who isn't shy about self-promoting and Pasdar will play a Wall Street millionaire.

Susan Misner will play Burns' wife.

Rob Corddry's sick and hilariously twisted 'Childrens Hospital' has been renewed for a fourth season on Adult Swim. The Web series-turned-TV hit will shoot 14 new episodes later this year that will air on Adult Swim in 2012.

"I'm very pleased and honored by this announcement," Corddry said in a statement. "I'm also very surprised, given that I write this show when I'm very, very drunk. Season four promises to be a cry for help."

'Children's Hospital' debuted as a Web series in 2008, and unlike other online-to-network jumps, has proven extremely successful. It has been the No. 1 show in its time period among adults 18-34, 18-49 and 18-24 for the past 10 weeks.

Owain Yeoman felt right at home on the set of 'Access Hollywood Live' (weekdays, syndicated on NBC) Friday, mostly because of Billy Bush's style choices. Bush was wearing dark slacks, a button-down shirt and a vest, which reminded Yeoman of one of his co-stars on 'The Mentalist.'

"I believe I have to also comment on your Simon Baker-esque wardrobe," said Yoeman. "I had noticed that you were channeling a little Patrick Jane." When the photos were shown side-by-side, there did seem to be a resemblance, even past the costume choice. "My goodness me, separated at birth," said Yeoman, calling Bush "Billy Baker."

Jon Hamm has joined the cast of IFC's 'The Increasingly Poor Decisions of Todd Margaret.' According to Splitsider, the 'Mad Men' actor will appear in five of the six Season 2 episodes.

Will Arnett and David Cross star in the comedy about an American sent to Britain to sell his company's energy drink. Season 2 premieres in January 2012.

Hamm is no stranger to comedy. He had an uncredited role in this summer's smash hit 'Bridesmaids' and has appeared in several episodes of NBC's '30 Rock.'

'The Mentalist' is about to wrap up its season, which means Robin Tunney should be able to take a break. But as she explained on 'The Talk' (weekdays, syndicated on CBS) today, that means being away from 'Mentalist' lead Simon Baker. That might be more disappointing to her dad than to Tunney.

"Everybody is in love with him," Tunney said. "It's not just women. I think that my dad has a crush on him. He'll call and he'll be like, 'I saw last night's episode. Simon took my breath away.'"

Tunney will be working on a film called 'See Girl Run' during the break, but she's a little worried about that, too, since she'll be starring opposite her dog. And her dog was cast first.

"He melts hearts," she said. "He's kind of a star." Tunney thinks the pup might upstage her in the movie. At least there might be a better chance that her father will notice her work.

It's CBS's turn to shake things up with its fall schedule, which the network just announced this morning.

'CSI' is finally getting the boot from its longtime Thursday night time slot in favor of the J.J. Abrams-produced 'Person of Interest,' while 'The Good Wife' is getting transferred from Tuesdays at 10PM to the highly competitive Sundays at 9PM slot.

The network's two new comedies will both get their shots after established shows, with '2 Broke Girls' airing after 'How I Met Your Mother' on Mondays and 'How to Be a Gentleman' landing post-'Big Bang Theory' on Thursdays. Interestingly, 'Rules of Engagement' is being pushed to Saturday nights.

CBS is saving the Robert De Niro-produced cop drama 'The 2-2' for mid-season (hopefully with a better name).

The full fall schedule is after the jump.

On CBS's hit drama 'The Mentalist,' you can count on Tim Kang's Kimball Cho to be the most steady, dependable and compelling sidekick on the CBI (California Bureau of Investigation) staff.

Off camera, the seemingly poker-face actor is relaxed, funny and loves to laugh about himself, the show and life in general. In a recent interview, we got just the facts from Kang as we chatted about his primetime success.

How does it feel to be on a hit show like 'The Mentalist'?
It feels pretty good. We're in a very enviable position and we've been very lucky to get the kind of response that we've gotten for the show. You know, we come into work everyday and do the best job that we can with the material that's given to us.

Thankfully, the audience has been and hopefully will continue to be receptive to it. It's a unique position to be in just knowing the reality of the landscape. So it feels really good to go to work everyday.

'The Mentalist,' which returns tonight at 10PM ET on CBS, is the type of show that is constantly in danger of falling into the tedium of formula. Actually, it really is a formula show -- the set-ups are often similar, the way Jane interacts with the suspects/victims is often the same, the solution revealed at the same time in the same way -- but it happens to be a well-done formula show.

So the question as we head towards the second half of the third season is this: is it becoming too formulaic?
