Trivia: The police car they use is marked as "K-9 - canine patrol". John Belushi's brother James was in a movie called K-9. He was meant to appear in this, but couldn't due to other commitments.
Trivia: When Dan Aykroyd and John Goodman drop off the Russians, the Perry Mason theme music is playing. Nia Peeples (Lt. Elizondo) was in a Perry Mason TV movie in 1990 (The Case of the Silenced Singer).
Trivia: The original pitch for the film was very different. John Belushi's brother Jim Belushi was initially supposed to star in the film as "Zee Blues," a long-lost third Blues Brother. The film would have been a tribute to the original that followed Elwood, Zee and "Mighty" Mack as they reunite the band to try to raise money to fix up the orphanage, which had fallen into disrepair. The character Buster also didn't exist in the original story. The studio rejected the pitch.
Trivia: The studio reportedly forced a number of changes during the production, including adding more fantastical elements (such as the Voodoo witch), toning the film down to a PG-13 and adding a child character to try to make it appeal to younger audiences. Director John Landis and star Dan Aykroyd hated these changes and nearly walked off the film, but begrudgingly agreed to remain on board. They both reportedly aren't very fond of the final film.
Chosen answer: No. We only know that he died sometime during his jail term. There's no more explanation after that.
