Jinxed! (1982)

Bette Midler is a Vegas singer who is married to Rip Torn, a career gambler. Rip is currently on a winning streak that is dependent on playing at the blackjack table where Ken Wahl is dealer. Midler and Wahl meet, have an affair, and plot the murder of Torn. The tone in this thing is all over the place. There’s spousal abuse, infidelity, suicide, and then out of nowhere a scavenger hunt. The three leads all seem to be in a different film. Midler is her usual effervescent, somewhat manic self. Torn isn’t menacing, but still a cruel, evil bastard. Wahl seems almost stoned, or at least a mindless air head. There is absolutely no chemistry in any of the three possible pairings.
