Jason Segel found that the most challenging part of filming "Jeff, Who Lives at Home" was playing Susan Sarandon's son.
"Holy moly, the hardest part of this movie was acting like I was not attracted to my mother," Segel told OnTheRedCarpet.com in a recent interview. "She's so foxy. It was a total honor to get to act next to someone of her caliber."
"Jeff, Who Lives at Home" follows a slacker named Jeff (Segel) who lives in his mother's (Susan Sarandon) basement and feels like he might have finally found his destiny when he helps his brother (Ed Helms) track his possibly adulterous wife (Judy Greer).
"It's a slice of what real life is like," Segel said of the film. "I'm more pragmatic [than my character], I think that life is what you make of it, for sure, and it's about taking control of your life... [If I met my character], at first I would be surprised by how much we look alike. I think I would have a hard time getting over that."
The film was written and directed by Jay and Mark Duplass, whose previous films include "Cyrus," "Baghead" and "The Puffy Chair."
"I learned a lot from watching them," Segel said of the Duplass brothers. "The way that they let their actors be their best was really inspiring. They give you guidance when you need it, but they really have confidence... I think it's all done in the casting for them and at that point, they let you play the part that you signed on for."
Segel is best known for his comedic roles in films like "Forgetting Sarah Marshall," "I Love You, Man" and "Bad Teacher," but the actor had a chance to stretch his acting chops with the dramatic role. Helms, who is best known for his role on "The Office" also made his dramatic turn in the film.
"It was exciting for both of us to get to stretch a little bit, you know, you always fancy yourself an actor and it's neat to see if you're actually right," Segel said. "What's great about the Duplass brothers, is that they want you to stretch yourself and they want you to be your best and they gave us that opportunity, so I think we're all really thankful about that."
Segel recently revived the Muppets franchise with his film, "The Muppets." His friend, "Flight of the Conchords" actor Bret McKenzie won the Academy Award for Best Original Song on February 26 for the film's song "Man or Muppet."
"That was an amazing, amazing day," Segel said of Oscar Sunday. "He worked so hard and we all worked so hard. I believe it was the first Muppet Oscar, so, you know, the big goal was to bring the Muppets back and I think we've done it."
Segel, who also stars in "How I Met Your Mother," recently said that he is not planning to write the follow-up film for the successful reboot.
"Jeff, Who Lives at Home" hit theaters on March 16. Watch a trailer below.
