9. Return of the Jedi connections

Since this was Luke after Return of the Jedi, the team used that film as a touchstone. For example, the sword fighting techniques he used in that movie were emulated but advanced a little bit, as one would expect. But, they weren’t quite polished, because Luke doesn’t have a teacher at this point.
Also—to give R2-D2 (who joins Luke on his rescue) the right look, the team sneaked in a specific animation that was filmed outside of Jabba’s palace in Jedi and used it in The Mandalorian.
