The funnyman, the star and co-creator of the original The Office Tv series, reprised his role as the cringeworthy manager last year (13) for a string of sold-out stage shows with his fake band Foregone Conclusion.
He recently revealed he had been filming behind-the-scenes footage at various gigs across the U.K. in the hopes of transforming the footage into a movie in the style of iconic rock parody This Is Spinal Tap - and now Gervais has signed a deal with Bbc Films to make the project happen.
Life on the Road will feature interviews with Brent over a decade after The Office ended in 2003 as he attempts to reinvent himself as a rock star.
A press release from Bbc executives reads: "We find out what Brent is doing now and what's happened in the last 15 years since his redundancy from his beloved (paper company) Wernham Hogg.
"He's a sales rep now, selling cleaning products up and down the country, but has never really given up on his dream of being a rock star."
The actor has since taken to his Twitter.com account to clear up any confusion about the mockumentary, writing, "Just to be clear, I am not making an 'Office' movie. I'm doing a documentary film about David Brent trying to be rock star. Just Sayin (sic)".
The film is due to go into production next year (15).
Gervais' David Brent character first appeared onscreen in the U.K. in 2001 when the first season of The Office aired.
