The producer admits he took on the film because his friends Ron Howard and Steven Spielberg were involved - and it featured "a lot of superstars", including Harrison Ford and Daniel Craig.

He says, "I don't like cowboys - or aliens! I said, 'We aren't really calling it that (Cowboys & Aliens), are we?' (The others said), 'Yeah, of course we are!' I was going, 'I don't get this at all'."

He adds, "We know what excellence is. We know what better food is versus not good food. But there's a rationalising process: 'That's good enough.' Anytime the light bulb goes, 'That's good enough', it's s**tty!"

But the film wasn't a flop - it grossed over $174 million (£116 million) worldwide.
