Tina Fey has revealed that she would hyperventilate during the action sequences of new animation movie Megamind.
The funny woman lends her voice, alongside Will Ferrell, Jonah Hill and Brad Pitt, to the character of Roxanne Ritchi in the movie and admits that she would get swept away during takes.
Speaking to MTV she said: "Having to imagine that you're up on top of a building and falling off, and being caught and swept back up, and trying to imagine all that.
"I can say that every time we had to do that stuff, I would kind of hyperventilate and get a little lightheaded."
The movie has already topped the U.S. box office, holding off comedy Due Date this weekend, and is due in UK cinemas next month.
fey has mixed her TV and movie roles this year as she has continued to work on 30 Rock whilst also starring in comedy Date Night with Steve Carell.
Megamind is released 3rd December.
