Hunter S. ThompsonAuthor, Fear and Loathing in Las Vegas and Hells Angels.
There have been two Hollywood attempts to turn Hunter's writings into movies. The first, Where the Buffalo Roam starring Bill Murray, was an astounding failure. However, it did have one unintended effect: in hanging around with Thompson for a while, it turned Murray into an unrepetant jerk for a good amount of time after production wrapped, affecting his relationship/interaction with the Saturday Night Live production.
The second attempt, Fear and Loathing in Las Vegas, was more successful, with the efforts of Terry Gilliam and Johnny Depp providing a near-exacting portrayal of the novel.
George W Bush once attended a Superbowl party hosted by Thompson, back in his cocaine days.
