Even though Tina Fey costars with Brad Pitt in the upcoming animated film Megamind, she still hasn’t met him, because they recorded their lines at different times. But she has a plan.
“I’m pretty sure we’re going to meet at some point,” Fey, 40, told PEOPLE at San Diego’s Comic-Con International on Thursday. “I’ve sent him over 100 letters saying that I’m pretty sure we’re going to meet. And 100 chunks of my hair. If that’s not a great gift, then one of us is crazy.”
Fey came to Comic-Con trying to prevent herself from using 30 Rock character Liz Lemon’s favorite exclamation of frustration: “Nerds!”
“I felt like I didn’t want to say anything that would get me in trouble,” she says, despite being prompted by a familiar gag from a former Saturday Night Live costar. “Jimmy Fallon emailed me and said ‘Nerd Alert! You’re at Comic-Con!’ ”
