Keith Lemon knows his favourite film, Rambo First Blood, so well that he can describe its entire plot barely drawing breath.

When asked what his favourite film is at the Stand Up for Cancer event in London on Friday night, the golden-locked comedian answered without hesitation: "Rambo: First Blood. Not all the Rambos, just the first one."

He then launched into a break-neck synopsis of the entire film from beginning to end from a scene where Rambo gets hosed down by enemy soldiers, which Lemon says he thought was "a bit homoerotic", to when the hero is attacked by an army of rats.
