 SPOILER: Alfred Hitchcock (I) (qv) was very uneasy about the  morphing of Normans face into Mothers at the end of the film. He  sent out three different versions of the film during its initial  release. The first version included the ending seen on all prints  today, the second contained no morphing at all, and the third  contained the trick at the end, yet also included it at an earlier  point in the film. When Sam Loomis comes back to the Bates Motel to  look for Arbogast, there is a zooming shot of Norman standing by the  swamp, looking very sinister. The third version of the film included  the subtle morphing of Normans face into Mothers at this moment.
