Admiral Firmus Piett is a fictional character from the Star Wars franchise, first introduced and portrayed by Kenneth Colley in the 1980 film The Empire Strikes Back.

Kasdan was aware that there was fun to be had in giving more depth and variability to his background characters, not only to help viewers identify them, but to remind his audience that much of the Empire consisted of people just doing their jobs.

[1] Although Admiral Piett's true first appearance in the Star Wars universe was one month prior to the release of the Empire Strikes Back in the film's novelization, he was brought to life to audiences around the world by British actor Kenneth Colley, who was cast in the role.

While in search of the Rebel base, under the command of Admiral Ozzel, Piett receives a suspicious transmission from an Imperial probe droid located in the Hoth system.

Although dismissed and ignored by Admiral Ozzel who wants proof, not leads, Piett supersedes his superior and informs Vader of the transmission; which in fact does turn out to be the hidden Rebel Alliance headquarters, Echo Base.

With the Falcon continuing to evade capture, Vader executes Star Destroyer Avenger captain Lorth Needa, conveying his displeasure as an ominous warning to Piett.

He first appears in the film when a covert team of Rebels, led by Han Solo aboard the stolen Imperial shuttle, Tydirium, attempt to transmit an older valid security code, to allow them shield access and entry to the forest moon of Endor.

He is given a much deeper backstory in these various media; As a young lieutenant, Piett impresses Vader with his skill and loyalty, and the Sith lord soon promotes him to captain of the Star Destroyer Accuser and makes him a member of the Empire's "Death Squadron".
