While I was researching this movie I learned a great piece of trivia. This was the movie to ever show toilet flushing on screen.
I think my favorite nod to Psycho comes in the movie National Lampoon's Family Vacation. On their first night on the road, Clark tears back the shower curtain and slashes at Ellen with a banana. The gratuitous boob shot (a teenage boy's favorite part of any movie) pales when Ellen tells Clark to go and wash his own front.
The beer pairing for this movie comes from a "new-to-me" brewery in Cincinnati called Madtree Brewing Company. You can listen to a interview I did with them HERE. Madtree is a young brewery and they have some "mad" brewing skills not to mention naming skills and all of their beers come in cans.
