Miller, who is non-binary and uses he/she pronouns, 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 string of legal issues that have put the actor in the headlines and questioned his future on the big screen.
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 was released from custody after posting $500 bail, according to local police.
On April 19, the actor pleaded no contest and was fined $500 to the disorderly conduct charge, court records show, and the harassment charge was dismissed.
Miller was ordered to appear in Vermont Superior Court on Sept. 26 for a hearing on the theft charge, the release said.
In light of the events, Warner Bros., the studio behind “The Flash,” which, like CNN, is owned by Warner Bros. Discovery, has faced questions about Miller’s future in the role of the iconic character.
Miller has previously appeared in multiple DC superhero films as Barry Allen/The Flash. Released on June 23, 2023, the film will be Miller’s first solo effort in the role.
Miller was last seen on the big screen in April’s “Fantastic Beasts: The Secrets of Dumbledore.”
