This next one might be tough, so I'll make it a 5 point question.
This game was for both the Commodore 64 and Atari 2600, although the memory limitation of the Atari reduced this 4-level game to only 3 on the 2600 system.
This game is a horizontal scroller, starts off on dry land for the first half of the first level, moves to water for the second half and remains water-bound for the remaining three levels.
Each level is named after a movie, and the protagonist is always the same in each one. In fact, the movies are still being produced today even after this Parker Brothers-produced game is only a memory.
What's the name of the game?
