Alien Vs Predator. Shonky film but nice oppo to do that gag about movie monsters being incredibly posh and 'lovey dahling' actors.
Idea had been brewing for a while. Just needed the right film to come along.
The mock interview, in which they campily bitch at each other was a chance to use all the Round The Horne/Julian And Sandie training. Worryingly easy to write.
The tuxedo bodies are me. The faces not as much.
Advantage of doing it for a crap film, it can die on its arse and nobody notices. Film promotion people are happy just to get their awful product featured.
