Yellowbeard (1983)

Watch Yellowbeard: Yellowbeard (Graham Chapman), a pirate's pirate, is allowed to escape from prison to lead the authorities to his treasure. He finds that his wife neglected to tell him that they have a son, now 20 years old and--shame of shame!--an intellectual. The British Navy, Yellowbeard, his son, and members of Yellowbeard's old crew all go after the treasure.
