Star Wars Episode I: The Phantom Menace (you knew it was coming sooner or later)

Say what you will about the flaws in this movie (and there are many), but it's hard to find fault with Liam Neeson. He always gives his all in whatever film he's in, and his characterization of Qui-Gon Jinn is no exception. His Qui-Gon is the Jedi we all want to see: quiet, dignified, wise in many ways, yet not afraid to "mix it up" when he has to (and he has the skills to back it up).

Qui-Gon was lifeless and boring, which I guess made him seem dignified when put on the screen next to the silly antics of Jar Jar and Anakin.

Obi-wan as played by Alec Guiness - that was dignified.
