The 1979 Disney sci fi spectacular "The Black Hole" didn't quite become the next Star Wars but the film did make an impression on a lot of us until the Empire Strikes back made us forget all about it.
The merchandising bonanza lead by Mego was particularly memorable. In the UK, the brand was handled by Louis Marx and they added some interesting items that sadly I don't think made it to market.
This one will always make me weep.
