Ryan Reynolds and Jake Gyllenhaal were told off on the set of 'Life' for "joking" about and costing the production money.

The Hollywood actors appear together in the sci-fi thriller, in which they must battle an aggressive extraterrestrial organism from Mars, and the 'Deadpool' star - who plays lead star Rory 'Roy' Adams - has revealed their budding "bromance" got them into trouble with the producers.

Appearing on 'The Tonight Show Starring Jimmy Fallon', the 40-year-old hunk shared how he and Jake - who portrays Dr. David Jordan - were shooting a scene which saw them "floating around on wires ... simulating zero gravity" and how they could not control their laughter.

He added: "Then when we would cut we couldn't stop laughing and joking and it was like, we wasted so much money.

Like literally, producers brought us to the side, in the corner, and were like, 'We need to talk to Ryan and Jake'.

"And they brought us in the corner and they were like, 'You guys need to cut it out. We are wasting so much money!' We're starting a bromance!"

Their co-star Rebecca Ferguson [Miranda North] recently gave an insight into the pair's great camaraderie on set - although those elements will be missing from the finished edit.

She said: "I realised [after seeing it] that the film that I saw is not the film I shot. On set it was a sort of very homey, fun environment, a lot of jokes."

Jake, 36, agreed describing the set "a wonderful place to be" despite the fear-filled plot.

He said: "We were laughing all the time. None of us takes ourselves that seriously, so there was a really wonderful spirit on set all the time."

'Life' follows a team of scientists aboard the International Space Station, whose mission of discovery turns to one of survival when they begin to conduct experiments a rapidly evolving lifeform that could have caused extinction on Mars, and now threatens the crew and all life on Earth.

Director David Espinosa has likened the film to Sir Ridley Scott's 1979 sci-fi horror classic 'Alien' but pointed out one key distinction that he hopes audiences make.

He added: "The realism of ['Life'] makes it different than other movies. Alien takes place 200 years into the future - this one could take place tomorrow."

Also starring in 'Life' are Olga Dihovichnaya, Ariyon Bakare and Hiroyuki Sanada, while 'Deadpool' writers Paul Wernick and Rhett Reese penned the screenplay.
