Treat Williams
From Wookieepedia, the Star Wars wiki.
Treat Williams (born December 1, 1951) visited Elstree Studios in England to see Carrie Fisher during production of Star Wars Episode V: The Empire Strikes Back. The two of them were photographed on set wearing Rebel uniforms and it is possible he is in the background in some shots at Echo Base. His name has been linked to two different characters named on Decipher cards, Jess Allashane and Jerrol Blendin, though neither of the men seen on these cards are in fact him.
