Walt Disney Pictures upcoming film, Tron: Legacy was the recipient of a script polish by none other than Pixar. According to EW, Brad Bird (The Incredibles), Michael Arndt (Toy Story 3), John Lasseter (Toy Story) and others were brought in to polish the script and give the fans the best story they can.

From EW:

In late March, the Tron filmmakers chose to show a very early working cut of the film starring Garrett Hedlund and Jeff Bridges to Pixar’s John Lasseter, Ed Catmull, The Incredibles director Brad Bird, Toy Story 3 screenwriter Michael Arndt, and others. The one-day exercise was done in advance of some planned re-shoots scheduled for June with the intent of beefing up the very things that Pixar is so good at: character, emotion, and theme.

Following the screening — and other viewings with various live-action filmmakers in Los Angeles — Disney hired Arndt and Bird to write some pages for the upcoming re-shoots, which lasted six days last month. Original writers Edward Kitsis and Adam Horowitz (Lost) were also integral in the writing at this time

Sean Bailey, Disney’s president of production said:

“Tron is very much Joe Kosinski’s vision, a vision which is thrilling to me and I hope is thrilling to the fans, What I give Joe and the filmmaking team immense credit for, is this was all born out of how do we give the fans the best movie we can. We were very fortunate that Pixar wanted to play a part in it.”

Tron: Legacy hits theaters on December 17th
