Ian Harding has joined Jane Levy and Brenton Thwaites in the zombie pic “Office Uprising.”

Lin Oeding is directing from a script written by Ian Shorr and Peter Gamble. The film is produced by Giulia Prenna (“The Evil Gene”) and William Clevinger.

“Office Uprising” is set inside one of the world’s leading arms manufacturers where a substance is slipped into the employees’ drinks by the board of directors to supposedly make them work more efficiently. Due to a slacker within the company, though, they are fed the wrong formula and start turning into homicidal maniacs — leaving the slacker needing to step up his game to rescue himself and his friends from the growing zombie plague inside the company compound.

Harding will play Dr. Frohm who works with Thwaites in research and development at the company. He also plays Levy’s boyfriend in the horror film.

Harding is best known for his role in Freeform’s “Pretty Little Liars” as Ezra Fitz, which is currently in its last season and begins airing in spring 2017. He is repped by Gersh and Authentic Talent & Literary Management.
