As we debate the merits of Batfleck and get ready for DC’s two biggest superheroes to finally meet on the big screen, it seems like the perfect time for a nice blast from the past.

Yes, a making-of documentary shot during the filming of Tim Burton’s 1989 classic Batman has surfaced online, and it’s is an absolutely fascinating lens into the film that truly launched the modern-day comic-book movie.

Though many revere Burton’s take on the Dark Knight now, it was a pretty risky film at the time — especially considering the decision to cast funnyman Michael Keaton as Bruce Wayne. The film sits down with Keaton, Kim Basinger and Burton himself to talk about what they were trying to make and the challenges of bringing the comic to the big screen.

The excitement is absolutely infectious, and no one seems quite sure that a “real” movie based on a comic can actually work. Living in a world where Guardians of the Galaxy is about to be a big-budget (potential) blockbuster, that's some legit nostalgia.
