However, it was Ali G himself that most of the crowds had stood in the rain for and he didn’t disappoint, arriving flanked by a group of girls wearing nothing but strategically placed cannabis leaves and high heels.
Ali G, aka comedian Sacha Baron Cohen, wore a white suit, floor-length, fur-trimmed cloak and matching crown for the occasion. He carried a mini-Oscar statue and was covered in his usual gold jewellery.
Speaking to NME.COM on his way into the Empire cinema, Ali G said: “They say this is one of the top three bestest films about the subject of Staines. Ever. I’ve been preparing all my life for this. I was born with a crown on my head and a crown on my… you know what I is saying.”
Star of TV series ‘The Office’ and recent NME Carling Award winner, Martin Freeman, also told NME.COM he plays Ali’s best friend in the film.
“It was great,” he said, “a good time had by all. He was an awful man though. If it wasn’t for the fact that I had some sort of sexual liaison with him about three years ago I think we would have fallen out long ago.”
