from Wookieepedia:
Jeremy Bulloch (b. 16 February 1945) is producer Robert Watts's half-brother. Bulloch played Boba Fett for most of The Empire Strikes Back and Return of the Jedi. The actual voice of Boba Fett, however—before being replaced with Temuera Morrison's in the Special Edition DVD—was Jason Wingreen.
He also played the role of Lieutenant Sheckil, an Imperial officer seen escorting Princess Leia Organa, Chewbacca, and Lando Calrissian through the corridors of Cloud City just after Luke Skywalker's arrival for his showdown with Darth Vader. 
Bulloch later returned for a cameo as Captain Jeremoch Colton piloting the Tantive IV in Revenge of the Sith.
