Here's why:
* Physical Differences: The bus driver at the beginning of the film is a middle-aged white man with gray hair, while the bus driver at the end is a younger African American man.
* Timing: The gap between the two scenes is significant. The first scene takes place in the early 1950s, while the final scene is set in the late 1980s.
* Humor: The repetition of the bus driver scene, despite the drastic differences in the characters, is meant to be funny and unexpected. It's a playful nod to the audience and a reminder that life can throw curveballs at any time.
So, while it might seem like a simple coincidence, the filmmakers intentionally used the bus driver gag to inject a dose of humor and whimsy into the film.
