Agatha Christie to become the next action hero.

Paramount Pictures has reportedly tapped Will Gluck (‘Easy A,’ ‘Friends with Benefits’) to take the director’s chair for the action-adventure tale ‘Agatha.’

Per Deadline, the spec screenplay was penned by Allison Schroeder (‘Mean Girls 2,’ ‘90210’) and surmises what really happened to British mystery author Agatha Christie during the 11 days she went missing in December of 1926.

Plot details are being kept under wraps but script has been described as a cross between ‘Sherlock Holmes’ and ‘Romancing the Stone.’

On the evening of December 3rd 1926, after quarreling with her then-husband, Archie, over his request for a divorce, Christie disappeared from her home, leaving behind a letter for her secretary saying that she was going to Yorkshire. Despite a massive manhunt, the author was not found until 10 days later. She was identified as a guest at the Swan Hydropathic Hotel in Harrogate, Yorkshire, where she was registered as “Mrs. Teresa Neele of Cape Town.” Christie never accounted for her disappearance.

Mary Parent and Cale Boyter of Disruption Entertainment are on board to produce with Benderspink’s Chris Bender, Jake Weiner, and JC Spink.
