Michael Keaton, one of the most decorated actors of the 90's and to this day, has portrayed some memorable characters in the past. One of them is the Dark Knight himself on two successive films, which he now chose to explain as to why there was no third.

One of the darkest, deepest heroes to date, Batman is a character and role that demands a heavy performance all throughout. However, such talent needs to be backed by a good script and storyline. This is the case that bothered Keaton in the past for the potential continuity which he respectfully declined.

According to his interview with CBS News in the past, Keaton said that the Joel Schumacher film was rather "awful" in his eyes, in which the actor did not hesitate to turn it over to a successor. The "Beetlejuice" star did not end there, as he explained how he felt that it was not about to do him any good.

The Hollywood Reporter noted that Michael Keaton found things fishy when the director asked "Why does everything have to be so dark?" Generally, the prior Batman films set a darker tone for Schumacher to follow and, after his choice, Keaton simply said that "it sucked."

The franchise took a while before it picked up from the lighter vibe of Schumacher's "Batman Forever" and "Batman & Robin," although it eventually did with the Christopher Nolan rendition. As for Keaton's latest work, he was recently confirmed to once again don a comic book character's garb. This time, he appears in the form of the Spider-Man villain Vulture in "Spider-Man: Homecoming."

"Birdman" is one of Michael Keaton's most remarkable recent works to date, showing how an actor struggles to live with a life that's no longer in the spotlight. It received numerous awards, including four Oscars and more than 300 other wins and nominations.
