George Loening Hickenlooper III[1][2] (May 25, 1963 – October 29, 2010) was an American narrative and documentary filmmaker.

[3][4][5] He was also the grand nephew of British-born conductor Leopold Stokowski through marriage to his great aunt, pianist Olga Samaroff (whose birth name was Lucy Mary Agnes Hickenlooper).

in History and Film Studies in 1986, Hickenlooper interned for the producer Roger Corman, and launched his directing career with Art, Acting, and the Suicide Chair: Dennis Hopper in 1988.

[citation needed] A short film written by Billy Bob Thornton Some Folks Call It a Sling Blade (1994), "attracted considerable critical acclaim" for Hickenlooper and was "[a] hit on the festival circuit."

[9][10] Despite initial reports that Hickenlooper had suffered a heart attack, the coroner ruled that his death was the result of accidental painkiller overdose, combining oxymorphone with alcohol.
