Cin Drallig is a background character from Revenge of the Sith: he is the Jedi fighting against Anakin as seen in the Temple security records He appears only for few seconds but I think this character is very interesting one first of all becuase he is played by the great Nick Gillard the great Stunt Coordinator and Swordmaster.
Cin Drallig, who played a very import role in ROTS videogame, is a very powerful Jedi master and a finest Lightsaber duelist; his duty on the Temple is to instruct Padawans in lightsaber fightings and he died heroically in trying to defend the Temple by Vader and his Clone Troopers.
Even if it appear for a very short time I think this character is more interesting than other background characters.

P.S.: well when I saw he deserves more attention I wasn't reafering to his role in the movie that couldn't be greater for obvious reasons( after all there are too many things to show in ROTS) but by hoe we fans "interact" with him and his role.
