Lyle Waggoner, the sable-haired heartthrob best remembered as the announcer and a comic performer in the early years of “The Carol Burnett Show” and for playing opposite Lynda Carter on the 1970s television versions of “Wonder Woman,” died on Tuesday at his home in Westlake Village, Calif. He was 84.

The cause was complications of cancer, his agent, Robert Malcolm, said.

Mr. Waggoner’s dulcet voice, square jaw and muscular physique made him seem cut out to be a leading man. But his most recognizable parts were in support of others — Ms. Burnett on her hit comedy-variety show, and Ms. Carter, who played Wonder Woman on ABC and then CBS in the 1970s.

Mr. Waggoner started on “The Carol Burnett Show” when it began in 1967 and stayed with the program for seven seasons, going from eye-candy announcer to important player in an ensemble cast that also included Harvey Korman, Tim Conway and Vicki Lawrence, in addition to Ms. Burnett.
