In the Pixar universe the part of Felicity Jones’ Jyn Erso in played by Merida, the Scottish princess from Brave.
Of course, the best choice may be Wall-E as K-2SO.
As Jyn Erso says in another she trailer, she rebels, and so does the princess who’s being forced to marry.
The rest of the Rogue One team, however, comes from every other corner of the Pixar universe, Mike Wizowski, Buzz Lightyear, and Art from Monsters University all appear.
