Ryan Gosling and Charlize Theron are reportedly being lined up to star as murder-charge athlete Oscar Pistorius and his late model girlfriend Reeva Steenkamp in a forthcoming biopic.

According to reports, a number of scripts are being developed in Hollywood which tell the tragic story of South Africa's one-time Paralympian hero and the fateful Valentine's Day morning in which his model girlfriend was shot and killed.

Pistorius, who is currently on bail, denies murder and claims he mistook Steenkamp for an intruder, reported Sun Online.

Sources say two scripts are being currently being developed with an announcement expected soon from one of the major film studios.

"You've got one of the world's most famous sportsmen under arrest and a beautiful young woman who meets a violent death. Scripts began doing the rounds within days of the scandal breaking.

"Ryan has the kind of quiet magnetism that would make this project work – plus there's some mystery about him. Although Ryan has been saying publicly that he wants to take a break from acting to relax, executives will be falling over themselves to woo him once the scripts are finalised," a source said.
