I saw Blues Brothers (1980) for the first time last night and I couldn't help but see many parallels between it and Ferris Bueller's Day Off (1986).
Both plots feature an adventure in the city of Chicago. There are some similar scenes such as the scene at the French restaurant and over-the-top musical numbers. The two movies had a very similar feel in many places and I can't help but compare them.
Were the creators of Ferris Bueller's Day Off inspired by Blues Brothers? Were specific parallels drawn intentionally?
