According to Deadline, Hetfield will play Officer Bob Hayward, a "no-nonsense Utah highway patrol veteran who was the first law enforcement officer to arrest Bundy in 1975 after pulling the killer over and discovering burglary tools in his car, but wisely suspecting much worse."

This will be his first time taking on a role of a different character in a flick, and we're stoked to see it.

He'll be joining Efron, who is starring as Ted Bundy opposite Lily Collins, who will be playing Elizabeth Kloepfer, Bundy's longtime girlfriend. Plus, actress Kaya Scodelario will be playing Carole Ann Boone, Bundy's ex-wife, in the upcoming flick.

Plus, John Malkovich is playing Judge Edward Cowart, who presided over the murder trial.

Take a behind-the-scenes look at some on-set photos, featuring Efron, Collins and more, here.
