Doctor in Trouble (1970)

Dr. Burke is in love with Ophelia but doesn't have time to propose to her as she leaves for a cruise to the Mediterranean. Also on board the cruise ship is an old school chum of Burke's who plays 'Dr.Dare' in a very popular TV series and who women flock to. Burke decides to join the cruise, but is first apprehended as a stowaway, and then becomes the captain's steward. For Burke, trying to talk to Ophelia is a hard enough task, but he meets some funny characters on board, such as a pools winner and a very stubborn captain.imdb
