The premise of the show is summed up in the opening credits sequence, narrated by Max, the Harts'
majordomo (
Lionel Stander), as he introduces the characters: Several early first season episodes originally included a slightly differently worded intro, with some alternative accompanying shots. This is replaced with the standard first season opening in
syndication and later digital releases: Beginning with Season 2 onward, the opening lines were slightly changed: Jonathan Hart (
Robert Wagner) is the
CEO of Hart Industries, a global
conglomerate based in Los Angeles. His wife Jennifer (
Stefanie Powers) is a freelance
journalist. Living the jetset lifestyle, the Harts often find themselves involved in cases of smuggling, theft, corporate and international espionage and, most commonly, murder. At their opulent
Bel Air estate, they are assisted by Max (
Lionel Stander), their shared mansion's loyal, gravel-voiced majordomo, who also helps with their cases. The Harts' beloved pet dog is a
Löwchen called Freeway, so named because he was a stray that they found wandering on the freeway. The Harts own a
Mercedes-Benz 300 TD diesel wagon, a dark green
Rolls-Royce Corniche convertible (replacing the Series III Bentley custom cabriolet in the first season), and a yellow
Mercedes-Benz SL roadster (1979 450 SL, replaced by a 1981 380 SL) with personalized California vanity plates "3 HARTS", "2 HARTS", and "1 HART" respectively. The opening credits sequence (stock footage drawn from the series pilot) shows Jonathan Hart driving a red
Dino 246 GTS. They also own a
Grumman Gulfstream II private jet, which is featured at the start of the opening credits. Critics have long noted that the premise of
Hart to Hart strongly resembles that of
The Thin Man films of the 1930s and 1940s, as well as
The Thin Man television series of the 1950s, which also depict a wealthy and glamorous crime-fighting couple who have a dog and no children. ==Production==
