The Squeeze (1987)

Harry Berg (Michael Keaton) is both a con artist and an actual artist -- he constructs large sculptures out of television sets -- but he is not particularly successful in either role. He owes some money, which gets him involved with Rachel Dobs (Rae Dawn Chong), a police detective who works with a collection agency. When Harry comes into possession of a strange parcel, both the con man and the detective find themselves wrapped up in a sinister corporate plot to fix the lottery.
