The Flash is currently speeding its way into cinemas worldwide. The film, which finds Ezra Miller's Barry Allen teaming up with Michael Keaton's Batman and Sasha Calle's Supergirl, is a multiversal epic packed with adventure, comedy - and a quite staggering number of cameos. It's also heavily inspired by a specific arc from the comics.
Flashpoint was a crossover event that ran through DC comics between May and August 2011. The core Flashpoint limited series, by Geoff Johns and Andy Kubert, focused on Barry Allen accidentally breaking reality after he undoes his mom's murder.
