Christopher Mintz-Plasse, "Superbad"
The actor was actually a real teen at the time of filming the Seth Rogen classic "Superbad." McLovin revealed that his notedly awkward sex scene wasn't fun for either party involved. “She got there, and I had fake sexual intercourse in front of her. Afterwards, we didn’t talk about it; we still don’t speak about that moment.”
Jennifer Lawrence and Chris Pratt, "The Passengers"
The scene between high profile actors Jennifer Lawrence and Chris Pratt in their space odyssey film, "The Passengers," was allegedly anxiety-inducing for Lawrence. She got "really drunk" before filming in order to make it through the guilt of kissing a married man because Pratt was still with wife Anna Farris at the time. After she left the shoot, she said drinking had "led to more anxiety when I got home, because I was like, ‘What have I done? I don’t know.’"
