In 2001,
Shrek producer John H. Williams founded his own studio, Vanguard Animation, which created
Valiant,
Happily N'Ever After,
Space Chimps, and a direct-to-video sequel of the same. Their website shows several other projects in the pipeline, such as
The Nut House (a heist film parody involving squirrels and acorns),
Rotten Island (adaptation of a book by William Steig, who also wrote the books that inspired
Shrek), an adaptation of Roald Dahl's
The Twits, and many more
are mentioned in a 2010 press release. However, other than an October 2011 announcement of
The Nut House, it seems Vanguard has vanished. Probably for the better, as another studio announced their own squirrel-based heist film
for a 2014 release.
