Transformers: The Movie (1986)
Forget the Michael Bay Transformers films – for those of a certain age, the ’80s cartoon movie was a defining childhood memory. A traumatic one – toy manufacturers Hasbro wanted to clear out the old Transformers inventory and introduce a line of new toys, so for the opening twenty minutes of the film, characters who'd merrily dodged laser blasts in the TV series were slaughtered in Peckinpah-esque scenes of carnage. All that and it featured Orson Welles' last screen role. As a planet-eating robot.
