Kevin Costner, Terry Crews will also star in the NFL dramedy.
Star talent is flocking to Ivan Reitman's Draft Day.
Diddy, Terry Crews and Chadwick Boseman have signed on to the film, which stars Kevin Costner as an NFL general manager making tough personnel decisions on draft day. The dramedy is set to begin shooting in New York this week.
Diddy is expanding his acting chops after a memorable turn in Get Him to the Greek, while rookie Boseman just flexed muscle as Jackie Robinson in the biopic 42. Crews was last seen on the big screen in Expendables 2.
Perhaps following 42's successful marketing strategy of releasing the baseball-themed film close to MLB opening day, Draft Day's release will likely coincide with football season next year.
