Ben Affleck is opening about why he left the role of "Batman" last year. He had portrayed the "Dark Knight" in Batman V Superman: Dawn of Justice and Justice League.

It was thought Affleck would direct and star in what became The Batman, which is now in production with Robert Pattinson in the leading role.

Ben Affleck needed new direction in his life

On his decision to leave the new "Batman" film behind, Affleck had this to say:

"It just happened at a point in my life when I lost interest in those stories. I'll go see [The Batman]. I think it's going to be great. I think [Robert Pattinson] is great."

But he says The Way Back, his new film, "is the kind of story I’m interested in telling now."

Ben Affleck is "Batman" no more

In The Way Back, Affleck plays a former basketball star who struggles with alcohol addiction and regret. He's given a chance at redemption through a coaching job with his old team.

The film features thematic parallels with Affleck's own life. He's been open in recent interviews, discussing the battles with alcoholism that led to a divorce from his wife, Jennifer Garner.

These issues contributed to Affleck's stepping back from "Batman" in 2017 and the eventual confirmation that he wasn't apart of The Batman in 2019.

The Way Back opens in theatres this Friday, March 6.
