Dust off your cowl, Batman Day 2023 is fast approaching. From exclusive comic releases to Bat-classics back on the big screen, we unpack Batman Day and how you can celebrate it.
Editor’s note: The original version of this story ran in July 2016, as Harley Quinn was about to make her big-screen debut in Suicide Squad. With Saturday designated as the annual Batman Day, and DC celebrating by giving Harley a co-starring role coinciding with her 25th anniversary, we thought it was the perfect time to revisit our first-hand account of the strange origin of one of DC’s strangest characters from the man who dreamed her up. In the early 1990s, Paul Dini was a writer for hire, cranking out scripts for the ground-breaking, noirish Batman: The Animated Series, when inspiration struck.
