10. Lohan experienced her own spell of bad luck while filming, revealing during a press conference, "I twisted my ankle, when we were shooting in New York, my right foot, and it's really ironic, because the film's called Just My Luck."

11. And Lohan broke out in a rash while filming the scene with an overflowing washing machine, saying, "I started breaking out in hives all over from the soap."

12. A prank Lohan pulled on Petrie ended up inspiring him to add a similar scene into the movie.

"I'll tell you one thing that scared the poop out of me. Lindsay is walking along with me on the street and turns a corner and walks smack dab into a glass wall," Petrie revealed during a press conference. "I thought, 'Oh my God, a broken nose,' and she's laughing at me. She did it supposedly on purpose."

13. Because Lohan had to kiss several different actors during the movie, Petrie allowed the star to have final say in casting. "There were times when I would even cast three or four guys and not tell the guys which one was the lucky guy," Petrie revealed. "They didn't know going into the scene. I just said to Lindsay, 'Pick, pick.'" 

Lohan added, "'Pick,' like it was so comfortable!"
