DreamWorks Animation and Universal Pictures are done with cartoon cavemen, at least for now.

Variety reports the two have abandoned plans for a sequel to the 2013 computer-animated adventure comedy "The Croods." The sudden cancellation came Thursday, leaving about 30 employees at DreamWorks Animation's Glendale, California, headquarters looking for new jobs.

According to the website, there had been doubts about "The Croods 2" even before NBCUniversal parent company Comcast purchased DreamWorks in April, reflected in the recent change of the planned release date from 2017 to 2018. Although there are no near-term plans for a sequel, a Universal source told Variety that the universe of "The Croods" may not be closed forever.

Starring the voices of Nicolas Cage, Emma Stone, Ryan Reynolds, Catherine Keener, Clark Duke and Cloris Leachman, "The Croods" centers on a prehistoric family forced to flee its cave after it's destroyed by a disaster that threatens to change their lives. The clan soon crosses paths with a resourceful teen (Reynolds), who offers to lead the way to a distant land safe from an impending disaster that will soon alter the world.

"The Croods" grossed more than $587 million worldwide on a $135 million budget, and launched a spinoff television series on Netflix called "Dawn of the Croods."
