I don't like the band, but I liked watching it because it was about Detroit!
Detroit Rock City... if that's the movie about the kids going to see KISS, it was filmed in Toronto.
I was walking down Queen St. one day, and saw a poster plastered to a sign post advertising a KISS concert at Cobo. Cool! I got about a block and a half before I remembered that Cobo was in Detroit.
The burger joint (forget the name of it, now) storefront stayed up for several months after the shoot finished before being torn down. Same with the nightclub entrance. Friends of mine thought they'd try the new establishments before realizing they were just sets.
You can tell all the scenes that were shot in Toronto because of the streetcar tracks -- Detroit never had any streetcars that I knew of.
Cheers,
