Intermedia has optioned Adam Alleca's sci-fi action-thriller spec "The Drowning Man." Based on Hideshi Hino's manga "Living Corpse," the story centers on a man who wakes up without a pulse and soon discovers that he is at the center of a macabre government experiment. Intermedia's Scott Kroopf will produce alongside Steven Schneider. Intermedia's Alison Haskovec brought the project to the company. Alleca, whose thriller "Home" is in development at Wes Craven's production company, is repped by WMA.
