A few years back, Pixar was working on a film called Newt.  The premise was about the last remaining male and female blue-footed newts on the planet who are forced together by science to save the species, but they can’t stand each other.  Sound familiar?  The film was scrapped after being too similar to Blue Sky Animation's Rio.  I think Pixar could have done more with the premise, but I guess we'll never know.  The best we'll probably get are leaked pieces of concept art.  We saw some back in 2010, and now more has been released online.  It's a great look, but sadly, most concept art for 3D movies tends to get watered down (remember how Tangled was supposed to resemble the artistic style of French Rococo artist Jean-Honore Fragonard’s painting “The Swing”?).  Either way, it's an interesting look at a film that never was.Hit the jump to check out the concept art.Via Bleeding Cool.
