All featuring living actors that may have either volunteered for cameos or wouldn’t have needed to be recreated in bad CGI. Non-Keaton, Non-Clooney characters from those Batman films.
There were so many other, more relevant options here. Here? These are often dead, always bad-looking CGI monsters. The CW’s Flash series did this with its own spin on Flashpoint, using more relevant cameos, and even getting Ezra Miller’s Flash to briefly appear there. What’s even worse is that there are so, so many other cameos they could have chosen here, if they wanted to do cameos at all, which I think is probably too meta to work anyway.
