According to The Hollywood Reporter, the suddenly very busy Jon Favreau will write and co-produce "Neanderthals" for Sony Pictures, an animated comedy that (obviously) takes place in prehistoric times.

"Sony Pictures Animation said Monday that Favreau will write and produce the CG-animated feature "Neanderthals," based on his original story. Further details about the plot line, the company said, "are being kept in a cave under a large boulder protected by a mastodon."

It will be Favreau's second collaboration with SPA; he also is voicing the character of Reilly, the beaver, in "Open Season," the animation studio's first full-length feature, which is scheduled for release Sept. 29 by Columbia Pictures.

Favreau also is the director of Columbia's live-action, sci-fi family film "Zathura," set to bow Nov. 11."
