Its quite often that many films use intertextuality. They borrow different ideas from each other for instance camera angles, soundtracks, methods of editing or aspects of Mise En Scene. These are all things you may recognise from some films that you have seen in others due to the fact that they have been borrowed.
Having watched 3 different clips of the following film; What lies beneath, Fatal Attraction, The stepfather and (student thriller) Succubus i noted down the aspects borrowed from the famous shower seen in'psycho'.
The one that stood out the most and the one i thought had the most intertextuality was The Stepfather. M.E.S - The white bathroom and the shiny kitchen knife.
Also the pulling of the curtain when he collapses into the bath after being stabbed in the neck.
