Elton John lined up for cameo in 'The Secret Service'

Sir Elton John is being cast for a cameo role in Matthew Vaughn's new comic book adaptation of 'The Secret Service', in a bid to turn it into a franchise.

The singer would feature as a hardman bashing bad guys in a huge fight scene.

A source told the Sun that the film is going to be a big British movie so Matthew wants to include some iconic British stars.

Brit star Colin Firth has already signed up to play the uncle of the main character - a young tearaway who is recruited by Colin into spy school.

Sir Michael Caine will also be starring, playing a veteran agent.

The original comics by Mark Millar will features cameos by stars like Luke Skywalker actor Mark Hamill and renowned director Ridley Scott.
