We did it three times really fast. Then it was over, just like that. We looked at each other like, Holy shit. We just did it. Any time I have a love interest in a movie, it’s my job to actually fall in love with them. While I was making this movie, I totally fell in love with Dan. - Dane DeHaan discussing his on-screen kiss with Daniel Radcliffe

I’m really bad at lying. I’m one of the worst liars I know. But if I can convince myself to believe something’s happening, I can do that.  

This scene originally was to be played as a very serious scene, however the actors kept cracking up with Benicio del Toro (as Fred Fenster) flubbing his lines. It eventualy became a constant laugh fest amongst the actors (leading Director Bryan Singer’s constant anger with the scene). But after reviewing the dailies, Singer realized that it actually played better into the character’s profiles.
