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). Jones also appeared in the critically acclaimed cable Western "Deadwood" (HBO, 2004-06) as a journalist in a corrupt pioneer town.
