Sexton penning 'Timecrimes' remake
The film will be a remake of Nacho Vigalondo's Spanish-language Los Cronocrimenes, a science-fiction noir story set in motion when a man steps into a time machine and travels half an hour into the past to prevent a crime.
The remake rights were snapped up in January after the film screened to a positive critical response at the Sundance Film Festival.
Steven Zaillian and Agnes Metre will produce the film. Sexton has previously worked on the science-fiction films Children of Men and an unproduced Logan's Run remake.
