Matt Damon and Ben Affleck's "Project Greenlight" is cancelled. The filmmaking competition docuseries is not returning for Season 5 after HBO decided not to renew it for another year.

Despite hopes to see "Project Greenlight" again for another season, Season 4 failed to amaze the crowd after the show garnered only 1.3 million viewers.  Aside from the unimpressive figure, HBO is not happy with the conflicts surrounding the production.

The show is reportedly surrounded by a couple of conflicts among the executives, which may have fueled HBO's decision to cut the docuseries. Producer Effie Brown is having disagreements with project director Jason Mann as well as with Damon.

"I'm not one to question," Damon told the Associated Press referring to the HBO programming while promoting his latest film "Jason Bourne." "They do such a great job, but we have to take it out again."

"The Martian" actor admitted that he thought "Project Greenlight" was great and so he was caught off-guard when he discovered that HBO decided to shut down the docuseries.  He shared that he is planning to start shopping to other networks or a streaming device like Amazon or Netflix, whichever would be a good fit for the show.

 "When we picked up a new season in 2014, we imagined a one season revival and decided in early 2016 another season did not make sense for us," Variety quoted HBO as saying in a statement. "We are proud of the show and were pleased with its run throughout the years."

It was the second time that "Project Greenlight" was cancelled after it was first axed in 2005.  HBO initially aired the show for two seasons between 2001 and 2003.  In 2005, the show was transferred to Bravo for its Season 3 until it was revived by HBO in 2015.

The reality TV series gave chances to aspiring directors to showcase their ability to helm a movie. The show has made impressive movies, including "The Battle of Shaker Heights," "Stolen Summer" and "Feast." It also produced PGL alums such as Pete Jones, Patrick Melton, John Gulager and Marcus Dunstan who are already showcasing their talents in Hollywood.
