Cogan, who turned 17 at the start of production in 1987, said in a 2016 interview with ABC News that fans still love to discuss the movie with him.
"I've had people say that this was their first film that their parents took them too that they remember going to the theaters to watch," he said. "[But for me], I think it’s about crazy. I think these kids leave the suburbs and they go into town and everybody they meet is absolutely crazy. It's a loony bin in the city."
"[Actor] Jonathan Ward was in there too, very close, and me and Jonathan had been up for many [of the same] parts before. I was like, 'He's the only one I could see as Brad. This is going to be an issue," he said with laugh. "I read for Darryl as well, and Anthony Rapp also read for Brad. But he is Darryl! You can't get another Darryl."
Most of the production, he said, took place in Toronto, though there were some moments that had to be shot on location in and around Chicago. One example: the scene in which Shue and the kids sing "The Babysitting Blues" in a famed nightclub, FitzGerald's.
"We went in on a Sunday to a recording studio in Chicago with Albert Collins and the Icebreakers. There was some structure for the song but they basically, in one or two takes, pounded out the music for it and Albert's part, brought us in, and [Shue] did her part with Albert and we did our back-ups," he recalled. "The next day, we're at the blues bar with that as playback, and we're lip syncing to it, but Albert Collins had never lip-synced in his life, so there was a learning curve."
"It was thrilling," he added. "We shot 13,000 feet of film in three days with three cameras!"
Another Chicago-centric scene featured a bit of movie magic. Coogan said the scene where his character is stabbed in the foot during a gang fight on the train was actually shot in reverse.
"We put the knife in, connected monofilament [fishing line], rolled the cameras, pulled it out, ran it backwards, and it - thunk! - goes right into the shoe," he revealed.
"I'm so thrilled that people have a soft spot for it," he added of the film. "You can't trade that for the world. You cannot buy it. And to be a very small part of something like that - it is really exciting."
