Mammoth Screen and Agatha Christie Limited are set to reshoot scenes of the BBC drama “Ordeal by Innocence” with Christian Cooke (“The Art of More”) stepping in to replace Ed Westwick, who has been accused of sexual assault by three women.

An adaptation of an Agatha Christie novel, “Ordeal by Innocence” had wrapped in September and was initially scheduled to air Dec. 26 as part of the Christmas lineup on flagship channel BBC One. But the show was pulled in the wake of the accusations made against Westwick, who is best known for his role in “Gossip Girl.”

The three-part series, co-produced by Mammoth Screen and Agatha Christie Limited, will reshoot all of Westwick’s scenes later this month in Scotland with Cooke and other cast members including Bill Nighy, Anna Chancellor, Matthew Goode and Eleanor Tomlinson.

The decision to recast and reshoot follows a similar move on director Ridley Scott’s “All the Money in the World,” in which actor Christopher Plummer took over the role originally played by Kevin Spacey.

Endeavor handles international sales for “Ordeal By Innocence.” A new British air date will be announced soon.

Meanwhile, the second season of “White Gold,” which Westwick was shooting when the allegations surfaced in November, is still suspended.
