The Shape of Things to Come (1979)
Jack Palance stars in this loose adaptation of the H.G. Wells novel.
Planet Earth is a wasteland, and what's left of humanity has colonized the Moon in domed cities. Humanity's continued survival depends on an anti-radiation drug only available on planet Delta Three, which has been taken over by Omus, a brilliant but mad mechanic who places no value on human life. Omus wants to come to the Moon to rule and intends to attack it by ramming robot-controlled spaceships into the domes. Dr. John Caball, his son Jason, Jason's friend, Kim, and a robot named Sparks embark on Caball's space battlecruiser on an unauthorized mission to Delta Three to stop Omus.
It's also very boring. It takes too long to get to the action, and when it does get there, it's not even comically bad (unless you count a bit of styrofoam from the collapsing set falling onto Jack Palance's head at one point during the climax).
Please. This is ripe for riffing. Jack Palance in space with an army of akward robots. Oh... And it's a Canadian star wars ripoff.
