Parting Shots (1999)

Harry Sterndale, a failed photographer, is given a diagnosis of cancer and told that he has only three months to live. After thinking things over, he decides that since he is dying anyway, he will kill or destroy all the people that ever crossed or hurt him during his life - after all, he will be dead anyway long before he can come to trial and get his just desserts from society. Harry hires an assassin to finish himself off in style, and even has time to fall in love with Jill. However, there's just one small problem with Harry's master plan - the cancer diagnosis is totally inaccurate and now he's got a hitman on his trail and several policemen wanting to talk to him about some murders...
