ET was on set with Tina Fey as the funny lady took on a role unlike any of her past characters in Whiskey Tango Foxtrot.

In the movie, the two-time Golden Globe winner plays a journalist sent to Kabul, Afghanistan on assignment. The war comedy is based on reporter Kim Barker's memoir, The Taliban Shuffle: Strange Days in Afghanistan and Pakistan.

Margot Robbie co-stars as a promiscuous international correspondent in the film, and Fey couldn't have been more pleased with her performance.

"She's so funny and so nice and she's homely, so that's hard," Fey told ET.

While the movie takes place in the early 2000s, Fey says that it will make audiences laugh regardless of their political affiliations.

"The movie itself is about journalism people working in Afghanistan and the insane lifestyle that they lead there, so it's not at all about the war or politics," Fey said. "Anyone who's ever worked there goes 'It's crazy there.'"
