Richard Coyle (“Prince of Persia: The Sands of Time”) and Sienna Guillory (“Resident Evil”) have joined the cast of Farren Blackburn’s “Dream On,” which includes a cameo from golfer Sam Torrance.

Pic, which is lensing at Elstree Studios and on location across Southeast England, has been adapted by Blackburn from John Richardson’s bestselling book of the same name.

The offbeat comedy drama is the story of Richardson’s obsessive pursuit of his dream to become a “scratch” golfer within 12 months.

Mark Pegg produces via his London-based production company Artifice on a £2.5 million ($3.8 million) budget.

Blackburn won a BAFTA last year for TV series “The Fades.”
