Sci-fi musical, TOOMORROW (1970), starring a young Olivia Newton-John. A throwaway 1970s Hanna-Barbera cartoon, but with real people. The sets are nice though, as are the primitive special effects.
I watched this film last night (it's on Amazon Prime in the UK) and it was a slice of cheesy silliness. Despite the alluringly tacky sci-fi scenes above, most of the film is a sub-Carry On-style comedy set at a fictional London college of the arts that's full of groovy gals and chauvinist chaps, but Olivia gives good chirpy Aussie chick and there's a hilarious bit at the end when the roof comes off the Roundhouse in Camden and everyone inside rises up into space via the magic of shoddy special effects.
