Miller, who is non-binary and uses the pronouns they/them, added, “I am committed to doing the work necessary to get back to a healthy, safe and productive stage in my life.”
Miller’s statement comes after a series of legal issues have kept the actor in the headlines and his big-screen future in question.
In March, Miller was arrested in Hilo, Hawaii, and charged with disorderly conduct and harassment after an incident at a bar, according to the Hawaii County Police Department.
Miller posted $500 bail and was released, according to local police.
On April 19, the actor did not contest and was fined $500 for the disorderly conduct charge, according to a court filing, and the harassment charge was dismissed.
Miller is scheduled to appear in Vermont Superior Court on September 26 on a burglary arraignment, according to the statement.
In light of the incidents, Warner Bros., the studio behind “The Flash,” which like CNN is owned by Warner Bros. Discovery, has been faced with questions about Miller’s future as the iconic character.
Miller has previously starred as Barry Allen/The Flash in several DC superhero movies. The film slated for June 23, 2023 is set to be Miller’s first solo effort in the role.
Miller last appeared on the big screen in “Fantastic Beasts: Dumbledore’s Secrets,” which was released in April.
