Hi Everybody,
I am trying to remember the title of a movie of the early 80's.

There where 3 boys in a treehouse as a spaceship landed.
One of the boys was a kick-boxer, the other guy was chubby und the other guy was smart.

Together they fought against alien/robot in that spaceship.

Do anyone remember??

I just found it. It's called Three Musketeers of Space - Starland trio.

I hope it helps
