Silent Witness has been a mainstay on the BBC with 22 seasons in 24 years, first premiering in February 1996. Oscar-winning actress Leo will star in and executive produce the potential Silent Witness remake, which Fox has given a script commitment to with a penalty attached. According to Variety, Silent Witness "follows two determined women with conflicting methodologies and their team while working for the Chief Medical Examiner in the shadow of a major departmental scandal involving corruption at the highest levels. With external biased pressures from all sides, they must use their scientific expertise to unravel clues in mysterious deaths while maintaining complete independence." Leo most recently starred in Showtime's I'm Dying Up Here and Fox's Wayward Pines.
