Trivia: With Michael Keaton reprising his role as Batman in the 2023 film The Flash, this film as well as Batman and Robin are no longer considered canon to the narrative of the original Tim Burton and Joel Schumacher films.
Suggested correction: I really think this trivia jumped the gun a bit, especially considering it was posted before "The Flash" even came out. "The Flash" was based all around multiverses, and there are also other diverging timelines based on the 1989-1997 Batman movie franchise, like the "Batman '89" comic books, which contradict not only this movie but also "The Flash." (Not to mention the George Clooney cameo in "The Flash," which is just an extra layer of confusion.) You can't necessarily just say in a vacuum that these movies are "no longer considered canon," especially because they were quite literally made to be canon. It's just going to come down to whatever specific film/TV/project you're watching and whatever it chooses to acknowledge. Unfortunately, multiverse stories have opened a weird Pandora's box where now continuity is almost meaningless.
I don't recall the source of where I got this info, but it makes me wonder if they were misled about the Schumacher films being removed from canon, if for no other reason than to keep George Clooney's cameo a surprise. If nothing else, I suppose this trivia entry can be amended to say that the Schumacher films can be considered to no longer be in the exact same continuity as the Burton films since Keaton and Clooney both appear in The Flash.
