With Avengers: Infinity War blowing up in cinema box offices across the world this past weekend, it seems that Marvel have another bona fide hit on their hands.

However, if one man had anything to do with it, there'd be an extra character in the mix alongside Thor, Iron Man et al.

Ryan Reynolds is known for his wry humour and the line between him and his character Deadpool has becoming increasingly blurred over the last few years - and that includes his latest tweet, too.

Reynolds shared a joke letter allegedly from Tony Stark aka Iron Man that appeared to be in response to his request for Deadpool to join the Avengers. 'No. Absolutely not," it read. "Go bother Prof X. No. Sincerely, Tony Stark."

SUCH a joker.
