Screenwriter Nick Pustay and his girlfriend went to Niagara Falls to watch the shoot. After a day of watching romance, he proposed to her and they married a short while later.
While shooting in Niagara Falls, Director Gregory Mackenzie married his girlfriend. The whole cast and crew attended with Producer Albert S. Ruddy giving away the bride, Sienna Miller the bridesmaid, and James Franco the best man.
During the shoot, Producer Dan Grodnick was always saying "that's fantastic!" so much, that he became known as "Fantastic Dan".
At the wrap party for the cast and crew, there was a Karaoke machine. James Franco got up and sang the theme song for El hombre araña (2002).
