Redbelt taps out on DVD

After four years of producing hit cable series The Unit, master director David Mamet returns to feature films with this mixed martial arts drama. Chiwetel Ejiofor plays Mike Terry, a jujitsu master who is baited and lured into deadly prizefights by some unscrupulous Hollywood types. As he realizes he’s in too deep with the wrong people, his battles, like Rocky’s before him, go from fights for money to fights for honor. Rated R.
