Paul said during an interview with 6Tribes: “Swearing is an art form and I had some really good minds on it. People were always giving me jokes and coming up with different creative ways to do it.
“When we first started (filming) I said to Jason (Statham), ‘Say f***k here!’ and he goes, ‘Oh, we can swear?’ Once I said yes they could swear then the floodgates just opened. He’s another amazing swearer and who knew Rose Byrne would be such a great swearer?”
During the interview, the American director was tested on a number of other British swearing terms to find out which ones he had heard of.
He revealed: “C**k Womble? I have not heard that one before. F**k Knuckle? Yes, I am aware of F**k Knuckle.
“Spunk Trumpet? Excellent! I think that’s the name of my new movie. I can see it now… ‘Susan Cooper in Spunk Trumpet!’”
The filmmaker also told 6Tribes that 'Spy' was party inspired by Carry On films explaining: “I’m obsessed with the Carry On movies. Would I make one? Hmmmm, it is tempting… but with Sid (James) gone I don’t know if you could and without Kenneth Williams too… “
'Spy' is out now, starring Melissa McCarthy, Jason Statham, Jude Law, Rose Byrne and Miranda Hart. Feig is also working with McCarthy on a new 'Ghostbusters' film.
