Filmed in 1984, The Gunrunner didn't receive a widespread release until 1989, thanks in great part to the presence of Kevin Costner in the cast. The future Oscar-winning actor is herein cast as the title character, an illicit "arms dealer" named Ted Beaubein. Set in 1926 Montreal, the story finds Beaubein trying to muscle in on the speakeasy racket, a decision prompted by his fondness for "speak" owner Maude (Sara Botsford). Things get hairy when Rosalyn (Mitch Martin), the socialite girlfriend of Beaubein's late brother George (Ron Lea), is kidnapped by the Mob. Attempting to deliver the ransom money, Ted discovers what the audience has known all along -- that no one in his particular circle of friends can be trusted.
