In 1981, O'Bannon helped create the animated feature Heavy Metal, writing two of its segments ("Soft Landing" and "B-17"). O'Bannon voiced his displeasure with his next big-budget outing, John Badham's Blue Thunder (1983), an action film about a Los Angeles helicopter surveillance team. Originally written with Don Jakoby, Blue Thunder also underwent extensive rewriting, losing some of its political content. He and Jakoby also scripted Lifeforce (1985), a movie based on Colin Wilson's novel The Space Vampires and directed by Tobe Hooper that veers from alien visitation to vampirism and an apocalyptic ending. It was not well received at the time, and was considered a box office flop. O'Bannon would again collaborate with Jakoby and Hooper for the 1986 remake Invaders from Mars. Purists considered it inferior to the 1950s original and it also performed poorly at the box office. O'Bannon also worked as a consultant for C.H.U.D., helping to create the design concept for the title creatures.
