Sully said he travelled with Nobby to Pinewood Studios.
“There was no limo, unfortunately, but a trailer,” he said.
“We headed down, and from there, we took some pictures in a room with about 50 cameras.
“He was a good boy, but quite a character, a bit like in the film.”
In one scene, Reggie and Ronnie headbutt a car.
“That was actually a crewman’s leg,” said Sully.
“I said sorry, but they said ‘no, no’, and they encouraged it, so I was chasing this man around with the sheep.”
He added: “It looks very like him in the film. I can tell that’s Nobby – they got him spot on, and it’s incredible what they can do now.”
