Tom’s small role in an episode of sitcom Happy Days led the show’s former star-turned-director Ron Howard to cast him as Allen Bauer in this romantic comedy.
Allen meets and falls in love with beautiful mermaid Madison (Daryl Hannah), but the course of true love isn’t entirely smooth for the unlikely couple.
This 1984 movie turned out to be a surprise hit and once again showcased Tom’s flair for comedy.
