MTv published an article on what makes “The Roommate” different from “Single White Female” (1992) which had the same plot.

Cam Gigandet explained of the very loose update of the 1992 Bridget Fonda/ Jennifer Jason Leigh that “the biggest change now is it’s a different time and people are dealing with things in a different way, and information is passed a different way. Everything has kind of changed, and I think this is a new version that deals with things that are going on right now.”

The story of The Roommate

“The movie is about Sarah — Minka Kelly’s character — who comes into college; it’s her first day, and she comes to the dorms and she meets me, her roommate Rebecca,” explained Leighton Meester. “We develop a friendship, and then it goes south and Rebecca starts to develop an unhealthy fixation on Sarah, and tries to merge with her and become very, very involved in her life.”

Cam Gigandet plays a good guy

Gigandet told MTV that he’s just happy to be playing a good guy for once — and is happy to watch the two actresses playing off each other to take their games to the next level.

“[Minka's Sarah] meets my character at a party, and we have this blossoming relationship,” he explained. “Recently I saw [Leighton] do a scene where she’s up waiting for Minka and I to get home from a date, so I drop her off at her dorm. And Leighton comes out with the creepiest look on her face! Just so much disgust, and she doesn’t even look at me. My character has never even met her before.”

“She’s just staring at Minka with these eyes that say, ‘There’s something off,’ ” he grinned, looking forward to the film’s September 2010 release. “It’s kind of wild to see. She’s kicking ass.”
