In 1970, Sheehan was a daily newscaster on KNXT-TV (later
KCBS-TV). Two years later (also on KNXT), he was the first television, film and stage commentator to host a television critique show,
Biting The Hand. In 1975, he was the first local newsman to ever work for two networks simultaneously:
America Alive! on
NBC and
The Big News on
CBS. In 1979, he hosted and produced the first Pay-TV monthly series in history,
Backstage in Hollywood on
HBO, which originally premiered on CBS television in the mid-70s. In the early 1980s, Sheehan produced and camera-directed
Pippin (with
Bob Fosse) starring
Ben Vereen and
Martha Raye-the first
Broadway musical filmed by cameras during live stage performance, for Pay-TV, cable TV and home video. Sheehan moved to
KNBC in 1984. While at KNBC, he was the first local entertainment reporter to host and produce his own series of network specials, including "Macho Men of the Movies" (with
Clint Eastwood,
Sylvester Stallone and
Arnold Schwarzenegger) and "Hollywood's Leading Ladies" (with
Julia Roberts,
Michelle Pfeiffer,
Sharon Stone and
Janet Jackson). Sheehan returned to KCBS-TV in 1994 and remained with the station until 2004. Sheehan hosted three national annual specials: "Summer Movie Magic", "Holiday Movie Magic" and "Academy Awards Movie Magic", syndicated to over 250 stations through his Hollywood Close-Ups, Inc. production and distribution company. ==Theatre==
