It's possible you're thinking of:
* A different movie: Perhaps the movie was from a different decade, or has a slightly different spelling for the character's name.
* A lesser-known film: There might be a movie with a character named "Chappy" that wasn't a major hit.
* A TV show: The character might be from an 80s TV show, not a movie.
To help me find the movie you're thinking of, could you provide more details? For example:
* What genre was the movie? (comedy, action, etc.)
* What was the character like? (hero, villain, supporting role)
* Any other details you remember about the movie? (plot, actors, etc.)
