> Since 2006, Pixar has been a subsidiary of Walt Disney Studios, a division of Disney Entertainment, which is owned by The Walt Disney Company.

>Pending the Disney acquisition of Pixar, the two companies created a distribution deal for the intended 2007 release of Ratatouille, to ensure that if the acquisition failed, this one film would be released through Disney's distribution channels. In contrast to the earlier Pixar deal, Ratatouille was meant to remain a Pixar property and Disney would have received only a distribution fee. The completion of Disney's Pixar acquisition, however, nullified this distribution arrangement.

Ratatouille was a Pixar movie. "Pixar was responsible for creation and production, while Disney handled marketing and distribution." Ratatouille was released after the merger was complete but I'd imagine the story was largely locked in.

Ratatouille was released in 2007, so would have been in production long before.

I guess, one of the last movies to have Pixar DNA through and through.

Turning Red and Lightyear are both Pixar movies

Disney owns Pixar.
