The Shaun of the Dead actor was stunned to see Cruise relaxing in the cooling contraption, which soothed his aching muscles during breaks on the set of their 2011 blockbuster Mission: Impossible - Ghost Protocol.

Pegg tells ShortList magazine, ""He had this special suit. You put it around the muscles that you've been working out and it ices everything. I mean, he's 49 now, and he was working out so intensively that it was important for him to be able to actually move the next day. So we'd be in the make-up chairs and he'd have this little jacket thing on that would go 'pffft' every now and then to ice his muscles.""

The Brit was keen to exercise with the Hollywood star, but admits he changed his mind when he realised how hard Cruise works to keep fit.

He recalls, ""One day I was like, 'I want to do your regime.' So he explained it to me and I think my reaction when he'd finished telling me exactly what it takes was, 'F**k that, Tom.'""
