Little Miss Sunshine and Star Wars

I can't help but see comparisons between Little Miss Sunshine and Episode IV or Star Wars in general. Here are the ones I've noticed:

Both feature well developed characters that engage in fun, interesting dialogue and back-and-forth banter as they all go on a fun adventure, mostly in a vehicle that's iconic to each film. They don't all get along at first, but by the end of the movie, they're all really close.

The family's VW bus keeps having trouble starting up; the Millennium Falcon keeps having trouble going to lightspeed.

Olive's grandfather, Edwin, trains her to compete in the Little Miss Sunshine beauty pageant, the climax of the movie. Obi-Wan trains Luke in the ways of the Force and guides him in successfully blowing up the Death Star, the climax of that movie.

The grandfather dies about halfway through the movie; Obi-Wan dies about halfway through the movie.

Richard, Olive's father and the vehicle's driver, butts heads with pretty much everyone else. The same goes for Han Solo.

Steve Carell's character is an intelligent, scholarly and sensitive homosexual. And then there's C3P0.
