Ananova:

A 75-year-old granddad has become a porn star in Russia after wandering into a blue movie audition by mistake.

David Bozdoganov wandered into the Gorodcki production company's studios after mistaking posters for new erotic actors as an advert for a muscle man show.

Director Alexander Plahov said: "We were auditioning for a new film and had a number of couples on stage simulating sex when I saw an old guy standing at the back.

"I wandered over to ask him to leave when I saw this massive package straining against his trousers. I thought, now this could be an original idea.

"And I was right - all the movies we've made with David have been huge successes."

The OAPs biggest hits have been The Old Neighbour and The Handyman at Work.

But Plahov added: "His female co-stars always complain because David believes in the beneficial power of garlic and insists on rubbing it on his erection before a scene and it's rather smelly."
