I think it was a made for TV movie. A playboy had to be married to inherite. His 'Uncle'? Got a priest to marry him. He marries and finds out the priest had been removed from practicing for some reason, so the marriage isn't valid. Rest of the movie is an attempt to get married for real, with evil uncle who will inherite if he doen't marry attempting to stop him. Only to find out at the end that the priest was OK and the first marriage valid

The bachelor? With chris o'donnell?
