American actor and comedian, born in 1938, who played the disguised Klingon spy Arne Darvin in The Trouble with Tribbles and returned to the role in Deep Space Nine thirty years later.
Charlie Brill is an American actor and comedian, born in 1938, long known as half of a comedy double act with Mitzi McCall.
In The Trouble with Tribbles (1967) he plays Arne Darvin, the officious assistant to Federation undersecretary Nilz Baris on Deep Space Station K-7. Darvin is exposed as a surgically altered Klingon agent who has poisoned the quadrotriticale grain, when the tribbles react to him as they do to every Klingon.
Brill reprised the part in the 1996 Deep Space Nine episode Trials and Tribble-ations, in which an older, embittered Darvin uses the Bajoran Orb of Time to travel back to K-7 and try to kill Kirk. He is one of a handful of original series guest actors to return to the same character in a later series.
