This film was made in 1981, and here is a link to imdb.com for it:

I thought I would recreate the MOC to make better pictures, but I lack a
lot of the parts, like the 40z gears, round bricks, motors, etc.
Maybe I could do a modernized version?
It (the MOC in the pictures) was a great inspiration for me at the time,
and a lot of contraptions resulted. I built catapults and handguns, 
alternate gearboxes for the 853 and 8860 cars, cranes and stuff. My 
brother built a working model of a helicopter rotor with tilting blades.
