If you ever needed more proof of just how important director Alfred Hitchcock is to filmmaking and film history, somebody made an entire documentary dedicated solely to one single scene from one of his movies. It also happens to be one of the most renowned scenes ever filmed.

I’m talking of course about the shower scene from Hitchcock’s 1960 horror classic, Psycho. The title of the doc, 78/52, refers to the 78 camera shots and 52 edits that went into crafting the scene. It was directed by Alexandre O. Philippe, and includes Guillermo del Toro, Bret Easton Ellis, Jamie Lee Curtis, Eli Roth, Peter Bogdanovich, and others dissecting and discussing the unforgettable sequence.

A new trailer for the movie has been released, and you can check it out below along with a previously released trailer which involves the brutal stabbing of a bunch of fruit.
