Conway as well moved into screenwriting in the 1980s, starting with the animated feature "Fire and Ice" (1983), co-written with Roy Thomas, based on characters created by Ralph Bakshi and Frank Frazetta. Conway and Thomas wrote the story basis for Stanley Mann's screenplay for the film "Conan the Destroyer" (1984). Afterwards, Conway and Thomas also worked on the script of a live-action "X-Men" film for production company Nelvana that wasn't produced because of distributor Orion Pictures' financial troubles and subsequent bankruptcy.
