Robert Conrad, who played an Old West update on James Bond in the hit 1960s TV series Wild Wild West, died Saturday at the age of 84. The actor died of heart failure at his Malibu home, according to family spokesperson Jeff Ballard. “He lived a wonderfully long life and while the family is saddened by his passing, he will live forever in their hearts,” Ballard said. After a brief career in film, Conrad was put under contract by Warner Bros. Television, and most of his most popular work was for the small screen. His first major success was on the detective series Hawaiian Eye, on which he starred as the half-Hawaiian private investigator Tom Lopaka. Conrad's most popular series was Wild Wild West, which creator Michael Garrisoin envisioned as “James Bond on horseback.” He starred as the secret service agent James West, who worked with the inventor and master of disguises Artemus Gordon (Ross Martin), to protect President Ulysses S. Grant and the United States Government. Conrad starred in a number of short-lived legal and crime dramas, before finding success again with the WWII-era series Baa Baa Black Sheep. Conrad was also featured on multiple episodes of Mission: Impossible, as well as The D.A., 77 Sunset Strip, Columbo, Adam-12, Maverick, and the miniseries Centennial.
