In the film, actor Topher Grace and Anne Hathaway are dating. When interviewing both actors it became apparent that their chemistry on-screen also translates off- screen.
"We have known each other for years," said Grace. "No one I have known longer in Hollywood that I haven't worked with then Anne."
"Me too," said Hathaway."So it is very funny because everyone is like, 'Wow, it seems like you guys have known each other forever.' I tell them if you count 16 as forever then it has been awhile."
Both Grace and Hathaway didn't mind the intimacy of their roles because of their long friendship.
"It's true, Topher's said it today that your first day of shooting you usually shake someone's hand and the next thing you know you are making out with them," said Hathaway. "So it is nice to be like, 'Oh, thank God, I've known you for a while.'"
"Which by the way was not a bad day at work," said Grace.
Julia Roberts, Ashton Kutcher, Eric Dane, Bradley Cooper, Jennifer Garner, Taylor Swift, Emma Roberts, Jessica Biel, Taylor Lautner, Hector Elizondo, Shirley MacLaine, Jamie Foxx, Jessica Alba and Kathy Bates also star in the film.
The film deals with casually intertwining stories of the heart that take place over the course of one Valentine's Day.
