Chris wasn't divulging any answers at Comic-Con, but he did downplay the real-life effects of a ScarJo smooch!
"She was a kid. She was like 16 or 17 years old. I've known her for over a decade now, so she's like my sister.
We have this little kiss scene. It will all make sense in the movie."
"My girl's an actor, too, so you kind of understand that. We're like, 'Hey, it's OK. It's what we do, what we do, what we do.'"
Of course! It's what she did, what she did what she did with Taylor Kitsch on Friday Night Lights! She knows all about doing your own lip stunts!
