The Fly III and rotting corpses

I was watching a film in the cinema, and the projectionist was Darth Vader, or possibly Stewie Griffin as Darth Vader, and everyone in the audience was Obi-Wan/Alec Guinnesses. Cut to Indiana Jones's Temple Of Doom, with the Devil somewhere about and all, and then I'm in 'The Fly 3' - I'm one of two Kenyan brothers and they and their wives are turning into giant Fly things. Then both brothers die I think and so I'm playing a corpse in this film - my brother and I are playing corpses hanging from this rigging, above a baying crowd, and every so often the rigging is lowered and the crowd abuse the bodies, and I'm turning green with putrefaction. I start getting tired and tell the director (who is Peter Jackson or similar), I say Look I have M.E., but he refuses to let me stop and I realise I was crazy to sign up for a whole movie shoot.

There's a long delay while backstage stuff is sorted and I'm worrying about how tired I'm getting; Angus Deayton (he's the director's friend) turns up on set, as does Sarah and I think Hannah. The cast rebels at being held rotting in rigging and goes to war with the crew: one side is armed with machetes and the other with guns, but I can't remember now which is which. And then I woke up.
