With New Line producing Shazam, there's been some doubt about how exactly the movie is going to fit into the DC Films Universe. Audition tapes may have referenced characters like Superman and Wonder Woman but given how disorganised Warner Bros. is when it comes to this world, who knows!
Well, some new set photos might clear things up as they feature a reference to ACE Chemicals. That Gotham City company is, of course, where The Joker was born and we got to visit there when he transformed the unhinged Harleen Quinzel into Harley Quinn in Suicide Squad. These posters for boxing matches don't appear to be tied into the plot in any way unless Shazam plans on fighting!
It also looks like Shazam might be set in Philadelphia as opposed to a fictional DC Comics location.
The chances of The Joker actually showing up in Shazam are between slim and none but this is still a cool Easter Egg and it will be interesting seeing how many others we get. What do you think?
