Hi,

I have memories of a movie and would like to know which it is. I watched it in 1988 and I was 4. To me it was horror (I remember someone was smashed with a stone on its head) but maybe.. I was just young. I remember:
–

• 1 to 5 adults and a bunch of kids hiding in a semitrailer
• They were stranded on a planet
• On the planet a guy was the boss, he had robots working for him. They looked metallic and were mostly inside.
• Robots with a horizontal oval shape – killing humans
• The Robots were marching and the adults were trying not t0 be seen.
• Some ‘doctor’ who could make his office/room become vacuum. He or someone else dies by the head exploding due to the vacuum
• He can avoid vacuum due to a glass helmet he puts over his head
• I remember an adult beeing killed by a robot smashing his head (it was scary to me)
• If I remember well the kids were hiding under a canvas in the semitrailer

Who can help me :)? Would be soo cool :)!
