Mick Bund can also be spotted in the "Batman" film - the one with Jack Nicholson as The Joker. He's in a few scenes but the one where he can be most easily spotted is as a newspaper seller. Derek Cracknell was involved in that film too.
Gave King Ralph a viewing (fair to say its no classic!), think I spotted Mick Bund in the Burger King scene, but gutted not to spot Sarah or Lawrence, so they were probably milling around in the background. I didn't realise that Derek Cracknell was Stanley Kurbrick's assistant director on several films, very impressive.
