Suicide Squad is certainly an odd movie for Warner Bros. and DC to position as one of the earliest introductions to their shared cinematic universe. As an offbeat ensemble picture focused primarily on B and C-list villains, David Ayer’s latest film would seem like a tough sell for audiences who have likely never read a Suicide Squad comic or are unfamiliar with a majority of the characters. Although the film does an adequate, if insufficient job of filling in the gaps, Suicide Squad is a film that truly rewards the observant comic book fan, as it’s packed with all sorts of references and hidden Easter eggs. While some of the following are easier to spot than others, you would certainly be hard-pressed to catch all of the following hidden details upon first viewing!
20. Harley Quinn and Joker – Alex Ross Cover
It’s hard not to notice the brief shot during Harley Quinn’s introductory sequence of the former Dr. Harleen Frances Quinzel and her Mr. J dancing arm in arm while dressed to the nines, with the Joker in a dapper suit and Harley in her traditional red and black jester costume. What you may not realize is that this shot is a direct callback to artist Alex Ross’ famous cover for Batman: Harley Quinn. It’s certainly a shame that we only get to see Harley in her original costume for this brief moment, but we’ll give it a pass considering it honors one of the greatest comic book artists of all time.
