VIDEO: Watch Mila Kunis and Justin Timberlake in the 'Friends With Benefits' Trailer

Movies have a strange way of coming in pairs, like when "Armageddon" and "Deep Impact" hit the scene in succession, or when "Antz" and "A Bug's Life" both hit theaters around the same time.

It's happened again, this time with the Justin Timberlake and Mila Kunis movie "Friends with Benefits" following the Ashton Kutcher and Natalie Portman film "No Strings Attached."

Here's a synopsis for the new film with JT and Mila: "A young female headhunter (Kunis) in New York convinces a potential recruit (Timberlake) to leave his job in San Francisco behind and accept a job in the big . Despite an attraction to each other, both realize they’re everything they’ve been running from in a relationship and decide to become friends… with benefits. It’s the perfect arrangement–until they realize there’s no such thing as no strings attached."

Sounds familiar, doesn't it? It's "Paul Blart: Mall Cop" and "Observe and Report" all over again.

But that's not to say that "Friends With Benefits" doesn't look good. The cast is terrific, as Timberlake has proven his abilities in "The Social Network" and Kunis has delivered a string of nice performances in films like "Forgetting Sarah Marshall" and "Black Swan."

The stars are backed up by names like Woody Harrelson, Emma Stone, Patricia Clarkson, and Andy Samberg, all very funny people. Plus, the script comes from Will Gluck, who directed the underrated "Easy A."

Check out the trailer for yourself, and decide: knock-off, or knockout?
