Taylor Kitsch
'Friday Night Lights'

"I'm known as one of the guys that throws a lot of curveballs to other actors and improvs a hell of a lot. I'll go way over the top. Like the episode ['Seeing Other People' during Season 2] where Saracen [Zach Gilford] was losing his virginity, I was talking as [my character] Riggins on the field, telling him I have an econo-sized bucket of lube in my garage, if he wants it. Or I'll go up to Coach Taylor [Kyle Chandler] all the time and start whining about some STD that I have as Riggins, and that [the] cream that he gave me made it worse, and I need to go have a shower."

Jake Weber
'Medium'

"[Patricia Arquette and I did an episode called 'Second Opinion'] a couple years ago where we had to put on prosthetic makeup. It took six hours to get ready for these scenes where we were supposed to be 25 years older, and one of our daughters was supposedly dying. And I show up on the set, and the woman's not wearing any of her old-age makeup. I was like, 'What happened to the whole thing with 25 years older and all this stuff?' And she was like, 'Oh, it just didn't look too good. It looked too strong. It looked too makeup-y, so I told them not to [apply] the prosthetic.' Well, how come nobody told me about this? So I ended up having to spend the whole day shooting, looking like an octogenarian, looking like Strom Thurmond. And she was all dewy-eyed like Candice Bergen with a few little crow's feet on the side of her face. I had jowls and sagging chins. Oh, I was furious at her."

Michael C. Hall
'Dexter'

"[In the Season 1 episode 'Popping Cherry'], there was a dream sequence that we shot where Dexter [Hall] has returned to the scene of his first murder. In the second season, we see a flashback, but it was once again this body that we used before. And it was without question the most remarkably realistic-looking corpse we've ever worked with. I mean, if I hadn't known that it was fake, I would have sworn it was real, even with my face inches away from it. And we all recognized it when they unveiled it. I was there with the crew, and everybody had flashbacks to their initial encounter with it the season before. It was like seeing an old friend who hadn't changed a bit."

Rainn Wilson
'The Office'

"I really liked the episode called 'Golden Ticket.' Steve [Carell] and I had a scene where we were walking down the sidewalk together, taking a stroll. I say, 'Guess what I'm thinking, Michael [Carell]?' And he says something. And then I say, 'No, I was thinking about how skin is the largest organ in the body.' And that was a completely improvised line. It just came out of my mouth. I knew [my character] Dwight needed to say something absurd that there was no way Michael could ever guess. And that's what I love about The Office—that we improvise off the script, and it just gets woven in."
