Zac Efron continues filming his part in "Extremely Wicked, Shockingly Evil and Vile" in Cincinnati, Ohio. On Wednesday, January 31, the 30-year-old actor, who plays serial killer Ted Bundy in the upcoming biopic, was spotted on the filming set being transported in a Utah State police car.

Wearing a gray suit and tie, Efron looked deep in thought as he sat in the backseat of the police car in some photos taken from the set. It's unclear what scene the "Baywatch" actor was filming. Two extras could be seen dressing as police officers, looking ferocious while sporting mustaches.

Bundy was executed in 1989 at the age of 42 at Florida State Prison after being found guilty on charges of assaulting and murdering multiple girls and women. He confessed to 30 killings, shortly before his execution. Authorities believed he might have been responsible for many more.

In "Extremely Wicked", the story of Bundy's crimes is told from the perspective of his longtime girlfriend Elizabeth Kloepfer, who for years refused to believe he committed the killings. Lily Collins plays Kloepfer in the film which has Joe Berlinger serving behind the lens.

In related news, it's been reported that Jim Parsons has joined the cast. According to The Hollywood Reporter, "The Big Bang Theory" star will portray Larry Simpson, the lead prosecutor in 1979 Miami trial that finally convicted Bundy.

Other cast members include John Malkovich as Judge Edward Cowart, who presided over Bundy's highly televised murder trial in 1979 and sentenced him to death, Jeffrey Donovan, "Maze Runner: The Death Cure" actress Kaya Scodelario and "Heathers" reboot star Grace Victoria Cox.

No release date has been set just yet. The film was penned by Michael Werwie, whose script landed on the Black List and earned the writer the Nicholls screenwriting award. Serving as producers are Michael Costigan, Nicolas Chartier, Ara Keshishian, Michael Simkin and Jason Barrett, with Voltage Pictures handling the distribution.
