If you believe exec producer Aaron Helbing, a speedster versus a super ape in an arena full of screaming gorillas is the best thing on TV ever. If you believe Cisco it’s the best worst video game ever. The truth is probably somewhere in between but it certainly sounds a lot of fun. Sadly there’s no footage of that actual scene in this featurette for The Flash 3.13 “Attack On Gorilla City” (airing in the UK next Tuesday on Sky 1) but it’s still a great tease. Spoiler alert, though – the vid gives away one minor twist that we’d have thought they writers would rather was kept for the episode, but maybe it’s not as crucial to the plot as it might look.
