Actors have been known to make unusual requests in their movie contracts, but when it came to working with Amanda Seyfried in his upcoming film In Time, Justin Timberlake had a romantic stipulation.
“I have a clause in my contract that says if you put someone as beautiful as Amanda in the movie, I have to fall in love with her,” Timberlake joked at a press conference for the film at San Diego Comic-Con.
The costars bonded over a grueling shoot for the futuristic action film, which has Seyfried and Timberlake on the run after his character is accused of murder, and the duo eventually spent time together “shooting” off camera as well.
