"I went to my agent and said, 'I want to do a drama,' and he said, 'You know I pitch you for dramas and no one sees it,'" Hader told Take Two.
People only saw him as the funny man from "Saturday Night Live." But after an opportune table read and a lunch with director Craig Johnson, the producers decided to take a chance on the star.
"So then there was two years of having money, not having money, ..." Hader says. That is, until Kristen Wiig, Hader's SNL co-star, was also cast in the film.
"And then the next day we got the money for the movie, because they went, 'You got Kristen Wiig in the movie?!'" Hader says. "And it was, like, yoing! And then they started throwing money at us."
Wiig and Hader play fraternal twins, Maggie and Milo, who haven't talked to each other in many years. When Maggie hears about Milo's attempted suicide, she rushes to his side, and that's when they start to repair their estranged relationship and help each other with their personal problems.
For Milo, a lot of his issues are related to having moved out to Los Angeles to become an actor, only to have failed. Hader elaborates:
"He goes out to L.A. and strikes out, big time, and has to come back home and live with his sister. And that's a hard thing to come to terms with. And he's seeking out his old teacher, who he had a relationship with, played by Ty Burrell. And he just wants that person who told him he was good, you know, to tell him he's good."
And that's something that Hader, himself, could relate to:
"I moved out to L.A. from Tulsa, Okla. And that fear of, 'Gosh, I hope I can make it out here.' ... Nothing's happening. I've been out for four years, and nothing's happened. And you just want that person who's like, 'No, no, you're good,' who validates you."
But even though it was a drama, it wasn't all serious on set. The two managed to have so much fun that Johnson had to rein them in.
"He was smart enough to say, ... 'Some of these things are hilarious, but now you guys seem like two people from 'Saturday Night Live.' ... You're kind of like, 'Why didn't Milo make it in L.A.? He can do all of these voices?'"
