X: The Man with the X-Ray Eyes (non-existent alternate ending of horror film; 1963)
X: The Man with the X-ray Eyes is a 1963 horror film starring film veteran Ray Milland as Doctor James Xavier, a man whose experiments give him ever-escalating vision powers that finally begin to drive him completely mad. It was directed by Roger Corman.
In the released ending, novelty long gone, and seeing perhaps through the universe itself, a broken James Xavier stumbles into a revival tent, where he heeds the evangelist's advice to follow literally the Biblical invocation to pluck out an offending eye. Xavier blinds himself to end his torment.
In the book Danse Macabre by acclaimed author Stephen King, he claims that Corman filmed an ending wherein the self-blinded Xavier claims in agony "I Can Still See!", his torment continuing and his sacrifice pointless.
However, in a 2017 interview with Roger Corman that looks back on his previous projects, he stated that this alternate ending does not exist, and that King had simply written an ending for the film after seeing it. However, Corman did like this idea and stated he wanted to remake the film with this ending.
