The Iron Lady opens in theaters nationwide tomorrow and in preparation, Meryl Streep stopped by Jimmy Kimmel Live! last night to promote the film.
Jimmy Kimmel himself was shocked to have the superstar grace his stage.
"I may have lied to the Make-a-Wish foundation and I'm fine, but it was a trick to get you here," Jimmy said on his show. "And I'm glad it worked."
Meryl plays Margaret Thatcher in The Iron Lady and prortrays her from her 40s to her 80s. The makeup helped her get into character, but was hard to get used to.
"It's weird," Meryl admitted. "You sort of look in the mirror and I felt like I saw my dad more than Margaret Thatcher. I mean really because I sort of look more like him than my mother."
While Jimmy had her on his show, he also got the chance to ask Meryl some questions he didn't think other peeople would ask her.
The last time you got drunk?
"Last night!" Meryl said with a laugh and crowd cheer.
