Guillermo del Toro may have taken home several trophies at this year’s Academy Awards ceremony for his film, “The Shape of Water,” but that hasn’t stopped him from planning his next steps. “SCREENPLAYS I have developed, fully written or co-written that have gone unproduced (so far),” the thread began.
