Number two was BATTLE BEYOND THE STARS (1980). One of the more competent Star Wars knockoffs, Monsterdon repeat offender Roger Corman serves up a scifi flick with some seriously psychosexual starship designs.
The film also features a sprawling cast full of some very silly characters -- the Texan space trucker with the belt-mounted booze dispenser that makes it look like he’s pissing in a glass and then drinking it is a real winner -- but Robert Vaughn as Gelt kind of steals the show. Overall it’s surprisingly solid and a lot of fun.
