Ryan Reynolds explains what he gave Brad Pitt to secure his Deadpool 2 cameo

Ryan Reynolds has explained the not-so-great lengths he had to go to in order secure Brad Pitt as a cameo in Deadpool 2.

Speaking to Entertainment Tonight at Comic-Con, Reynolds said Pitt only asked for one simple thing - a cup of coffee.

"I was told all he wants is a cup of coffee and I said, 'Like a franchise or just one individual cup of coffee?'" he told ET.

"I was told one individual cup of coffee, which was really his way of saying, 'I'm doing it for nothing.'

The Deadpool 2 star called the act from his fellow Hollywood A-Lister "a total solid", especially considering Pitt's fleeting role in the film. 

The comedy superhero film is filled with surprise appearances by a host of famous faces, but Pitt's role as - spoiler alert - Deadpool ally 'The Vanisher' was ironically transient.

"I just loved it, because what's more irresponsible than taking one of the biggest movie stars in the world and giving him a role that is utterly wordless and invisible with an exception of three frames of film?"

"Yeah that's kind of amazing," he said.

To date, Deadpool 2 has brought in over US$732 million in box-office sales world-wide.
