So, three films I cannot remember the names of…
1) A kid with a pet bug (sees his family killed?) and runs away in a spaceship with a knock-off Han-Solo.
2) Human space police in a super new ship run into a cyborg warrior. Then the cyborg warriors spaceships start to combine and the humans ship is the final part of a super-weapon.
3) Alien kid living with an old man runs into bad guys at a satellite dish (radio telescope?) that are cloning people with their machine that includes a big drawer. The kid ends up in the drawer at one point. I think this was one of at least two films with the alien kid and the old man.
I saw all these as a kid in the 80’s and early 90’s and cannot for the life of me remember the names of the films.
Please, won’t someone put me out of my misery…!
