There's a simple reason why Jennifer Garner agreed to the role of Diana in the upcoming movie Wakefield. It spoke to her.
ET caught up with the 45-year-old actress on Thursday at the film's premiere in New York City, and she explained why she thinks Wakefield will resonate with audiences. In the movie, Bryan Cranston plays a man, Howard Wakefield, who has a nervous breakdown, and leaves his wife (Garner) to go live in his attic for several months.
"I think anyone can imagine just the desire to drop out of their own lives," Garner noted. "It's just to actually do it, to follow through and to live outside of your life [while] watching your own life for a year, [that] is pretty out there."
As for whether she's ever thought of running away, the mother of three replied, "No I like my life, I'm not looking to go anywhere."
Garner -- who looked stunning at the premiere in a strapless black and gold Oscar de la Renta dress -- also praised Cranston for his performance in the film, calling him "the most fun."
"He's such a goofball, and he went through so much making this movie," she recalled. "He was constantly putting a beard on, putting dirty nails on, he got skinnier and skinnier all the time. I don't know why I work with these guys who are all getting skinny! But whatever, he did, he really went through it."
