Relatives in a movie

I watched The Last Starfighter in class today. It was a very kinky 80s movie with some pretty cool computer imagery for its time. The cast was very good and kept things fresh despite the fact that they all looked like bunnies that were all related. The main character Alex, looked like a dirty incestuous fiend whenever he made out with his 'girlfriend' Meg. Our little couple looks like they could be siblings as they linger about their cozy trailer park. Alex's mother looks almost like an older version of Meg, as a matter of fact the only person who didnt look related to everyone else in the trailer park was Otis, the man who ran the shop.

Pic related, its my favorite character, Grig. He is my favorite from this movie from the way he mentors Alex as he is going through trying times.
