Mr. Weems lived in Marblehead, Mass., and was traveling from Boston to Los Angeles to attend a meeting with Energy Star, a client of Interpublic Group of Cos.' Mullen Advertising, Wenham, Mass.
Some of his most recent work included an anti-smoking campaign for Havas Advertising's Arnold Worldwide and Tyco International via Interpublic's Bozell, Boston. Earlier in his career, he worked for September Productions, Boston.
"When we couldn't get Bill on a project, it was always a big disappointment," Bill Drake, creative director at Mullen, told AdAge.com. "We started making sure we booked him well in advance -- first hold, second hold, it took all kinds of 'holds' to get our 'Weemsy.'
"This mild-mannered, sweet-hearted, genteel man always managed to introduce a special style of decorum and order into the ever-present chaos of television production," Mr. Drake said. "He had this humble, disarming dry wit that so many times turned a long trip into a hysterical laughing session. Bill will be forever missed and remembered by us all."
Mr. Weems is survived by his wife and daughter. His age was not known.
