The musicians play themselves in 90-minute action adventure Bula Quo!, and Parfitt has revealed he was sidelined from several scenes after sustaining a leg injury.
A stuntman stepped forward to take over his role, donning a blond wig to play the rocker, but Parfitt never found out his name and is now hoping to track him down to thank him and hand him a copy of the finished film.
He tells Britain's Metro, "I'd kind of hurt my leg doing some stunts. So we got this stunt double in and he's a black guy with a blond wig on and, you know what, from that day to this I still don't know his name.
"We were doing a scene on a river and he had a boat so he had to play my stunt double. How on earth they were going to film a black guy playing me I do not know. There's smoke and mirrors and all that, but that's taking it too far... We got away with it anyway."
