An accomplished American actor of both stage and screen, Jeffrey Jones became known for a series of frequently hilarious characters ranging from the bumptious, to the blundering, to the merely bewildered. Jones gained widespread recognition in the period biopic that essayed the short, tumultuous life of master composer Mozart, "Amadeus" (1984) starring to riotous effect as the preening, child-like Emperor of Austria. As notable as that role was, he topped himself with a turn as a high school principal obsessed with catching hooky-playing hero Matthew Broderick in John Hughes' "Ferris Bueller's Day Off" (1986). Jones found a professional home as part of director Tim Burton's unofficial acting troupe in efforts like "Beetlejuice" (1988), "Ed Wood" (1994) and "Sleepy Hollow" (1999). Sadly, his professional credits were eclipsed for a time by child pornography charges leveled at him in 2002, part of an investigation that included fellow Burton collaborator, Paul "Pee Wee Herman" Reubens. Jones resurfaced in the critically acclaimed cable Western "Deadwood" (HBO, 2004-06) as a journalist in a corrupt pioneer town, but appeared in little else in the second half of the decade. Having fashioned a career in which he frequently brought humanity and humor to unlikable characters, Jones' unsavory personal exploits threatened to derail a respectable career that had made him a welcome fixture in American cinema for 20 years.
