Rooker garnered critical acclaim for his disturbing performance in John McNaughton's "Henry: Portrait of a Serial Killer" (1990). Filmed in 1986, and shelved until 1990, the film was finally released with an "X" rating due to its intensely realistic violence. Rooker's performance suggested the inner workings of a deeply disturbed yet outwardly normal man. Eschewing flashy characterization, Rooker crafted a human monster that truly unnerved the viewer. He has since been given strong supporting roles in the Tom Cruise vehicle "Days of Thunder" (1990), Oliver Stone's "JFK" (1991) and "The Dark Half" and "Cliffhanger" (both 1993).
