This year's NFL draft is serving double duty.

The first, and most important, purpose for Thursday's event at Radio City Music Hall is for NFL teams to select college players and build towards their future.

But don't be surprised if you see a few extra cameras. That's because production of the upcoming movie Draft Day, starring Kevin Costner and Jennifer Garner, is set to begin at Radio City Music Hall. The film, in which Costner plays the GM of the Cleveland Browns, depicts the difficult personal and professional decisions that an NFL executive must make during a 24-hour period of the NFL Draft.

The film will feature a host of football players and on-air personalities, including Jon Gruden, Mike Mayock, Deion Sanders, Rich Eisen, Mel Kiper and Chris Berman. Several of the players, like free agent wide receiver Ramses Barden and New England Patriots punter Zoltan Mesko, participated in the NFL's second annual Pro Hollywood Boot Camp. NFL defensive end-turned-actor Terry Crews will also play a role in the movie.

Houston Texans running back Arian Foster -- who made a cameo in an episode of Hawai'i Five-0 -- will play a prominent role in the movie.

The movie, directed by Ivan Reitman (who produced Space Jam), will also feature '42' star Chadwick Boseman and rap mogul Sean Combs.

After Thursday, production will move to Cleveland for on-location shooting.
