Nicholas Lyndhurst is set to play his own dad in a prequel to Only Fools And Horses, it was announced today.
The 47-year-old actor has signed up to play "art connoisseur" Freddie "The Frog" Robdal in the BBC1 series. He is the father of Rodney Trotter, the character Lyndhurst played in the original show.
Programme-makers have begun filming on the series, Sex, Drugs And Rock 'n' Chips, which looks at the early years of Del Boy and Rodney and their pals.
Quadrophenia and EastEnders star Phil Daniels has been cast in the show as Del's granddad, Ted.
Writer John Sullivan said: "Sex, Drugs And Rock 'n' Chips hurtles us into the rough and unglamorous world of London in 1960 to discover the circumstances that led to Del and Rodney Trotter turning out the way they did.
"Nick Lyndhurst is a comedy genius and I can't think of anyone better suited to bring the shady but charming Freddie Robdal to life, and James Buckley (who plays teenage Del Boy) has a tough act to follow but is sure to do for leather bomber jackets and winkle-pickers what David Jason did for camel-haired coats and cocktail umbrellas."
Buckley is best known for The Inbetweeners.
Bad Girls' Kellie Bright plays the boys' glam mother, Joan Trotter. Soldier Soldier's Shaun Dingwall plays her husband Reg Trotter.
The series will see Joan not-so-happily married and living in Peckham with bone-idle Reg, when Freddie "The Frog" is released from prison and comes back into their lives.
The comedy drama also features the teenage versions of Only Fools And Horses favourite characters Boycie, Trigger, Denzil and Roy Slater.
