Hear Alison Brie's British accent in 'The Five-Year Engagement' trailer

alison-brie-five-year-engagement.jpgThe just-released trailer for the new rom-com "The Five-Year Engagement" is completely charming, which is reason enough alone to watch it. Emily Blunt and Jason Segel star as an engaged couple who have to keep pushing their wedding back when job opportunities arise.

It looks funny and adorable and a perfectly nice way to spend an hour and a half. But there's another reason you should probably check out the trailer, and that's "Community" and "Mad Men" star Alison Brie rocking her best British accent as the sister of Blunt's character. 

We always get nervous when American actors try the Queen's English, but she seems to do a pretty good job here. At least from the 2.5 seconds we see in the trailer. Watch it below. "The Five-Year Engagement" comes out April 27, 2012.
