Loved that movie back in the day.

Favorite line "We're not playing for 3-IN-ONE oil."

I think I read that the three droids in Silent Running -- Huey, Louie, and Dewey -- were inspiration for R2-D2.

Yeah, I can see that. They were great little droids. Got a lot of emotion out of a little beeping machine. Come to think of it, R2-D2 also.
