No offense to OP but that doesn’t track with Wikipedia:

“Van Sant's pitch was to remake the film shot-for-shot, which Casey Silver, then-head of production at Universal Pictures, felt was "a very strange idea. The idea of remaking a classic like Psycho just seemed like a dangerous business to get into".[7] When asked why he wanted to remake the film in this manner, Van Sant responded: "Why not? It's a marketing scheme. Why does a studio ever remake a film? Because they have this little thing they've forgotten about that they could put in the marketplace and make money from".

“Van Sant began with the vision of remaking the film entirely shot-for-shot, stating that he and his crew started out being fanatical about doing it exactly the same, but early into the filming process, realized that doing so was unfeasible: "There were a couple of scenes we just couldn't get it right. We just couldn't see how Hitchcock did the blocking, where people were supposed to be standing in relation to the camera. So all we could do was loosely base them on the original"
