Zac Efron has signed up to produce and star in a new untitled workplace comedy from the writer of his former motion picture 17 Again.

While details of the project are limited, it is confirmed that Jason Filardi will write the script, according to British Empire magazine.

The High School Musical actor recently acknowledged his relationship with longtime girlfriend Vanessa Hudgens for helping him to evade the pitfalls of Hollywood.

"It helped me through quite a bit," he said. "There are myriad distractions to fall into in this business.

"To have someone to share with and to relate to is a very valuable gift."
