One of the character's called Spunkmeyer. The original choices of Jizzsmith and Cumgold were considered too silly.
Filmed mostly in west London. Coulda saved a fortune on set design by filming in Croydon.
Years ago there was an Aliens themed interactive attraction in Trocadero in London. A guy I knew went on it. There was a part where you're in a lift with a few marines and they enacted a variation on the "Eat this" scene. The actor playing one of the grunts had to break character to tell the drunk guy in the corner to stop pissing in the lift.
