Career
He had a variety of roles in film, television and theatre including as Red X-Wing Squadron Leader Garven Dreis in Star Wars Episode IV: A New Hope. He retired from acting due to manic depression. Henley has appeared in a number of film, television and theatre productions.
These included episodes of Z Cars, unidentified flying object, The Avengers and Randall and Hopkirk (Deceased) and a three-week run of Henry V in 1968 in which he played the lead role.
He is best known for his role as X-Wing pilot "Red Leader" (Garven Dreis) in the 1977 film Star Wars Episode IV: A New Hope, a role for which he was mistakenly credited as "Drewe Hemley". Henley used an American accent for the part.
The role had limited physical movement as Henley"s character remained in the cockpit for much of the film which Henley found difficult. Unlike many of the actors in A New Hope, Henley"s performance was not dubbed in post-production.
Henley interpreted his character as an experienced battle veteran and so opted to play him without any excitement in his voice.
Director George Lucas disagreed with this so they compromised so that Red Leader would at first be formal but as the battle progressed become more excited. The performance was Henley"s final one on film, as he was diagnosed with manic depression shortly after completing his part and he retired from acting. When the Special Edition cut of A New Hope was released in 1997 it featured an additional scene of Henley in which he talked with Luke Skywalker (Mark Hamill) and Biggs Darklighter (Garrick Hagon).
Henley was pleased with the scene"s addition, although his cr was not corrected.
