This has always been in my "Top 3" list. Only a few years ago did I realize that it's a musical.
There's an interview with a story about Dan Aykroyd delivering his screenplay to his friend for review that is priceless. It was the size of a phonebook, with detailed descriptions of everything.
Another fun moment, "Danny, this scene can't be shot. Where are we going to find a mall to destroy?" Then, shortly after, a mall closed and went up for sale. 🥳
