Some people suggested that the Krofft brothers were influenced by marijuana and LSD, although they have always denied these claims. In a 2005 interview with USA Today Marty Krofft said; No drugs involved. You can't do drugs when you're making shows. Maybe after, but not during. We're bizarre, that's all. Referring to the alleged LSD use, Marty said in another interview; That was our look, those were the colors, everything we did had vivid colors, but there was no acid involved. That shit scared me. I'm no goody two-shoes, but you can't create this stuff stoned.
The Kroffts also favored quirky superhero stories, often with children involved as the heroes or part of a hero team. Particularly visionary and popular Krofft productions have included Land of the Lost (1974), Electra Woman and Dyna Girl (1976), Wonderbug (1976), The Bugaloos (1970), Sigmund and the Sea Monsters (1973), The Lost Saucer (1975), and Lidsville (1971).
In 1976, a developer asked the Kroffts to develop an amusement park for the new Omni International complex in downtown Atlanta. The World of Sid and Marty Krofft was the world's first indoor amusement park, but due to poor attendance it was closed after just six months. The Omni International building that contained the amusement park was renamed to the CNN Center when the site was converted to the present CNN headquarters.
The Kroffts were also responsible for a large number of prime time music/variety programs. These shows also tended to employ a reliable formula, in this case featuring a celebrity host or team of hosts, weekly celebrity guest performers, flashy and colorful sets, and frequent interludes of scripted banter and gag-driven, "corny," good-natured sketch comedy.
The Kroffts have occasionally departed from their successful formula, notably a new version of Family Affair (2002), and the political puppet satire D.C. Follies (1987). The team has recently attempted to update some of their most popular series for a younger generation, including new versions of Land of the Lost, Electra Woman and Dyna Girl, and H.R. Pufnstuf.
The Kroffts are often acknowledged for the ambitious vision and creativity of their projects. In addition to their recognizably colorful and hyper-kinetic programs, they often created children's shows with complex stories, unusual protagonists, uniquely modern sensibilities, or with darker or more action-themed tones than most children's shows.
The Kroffts' "camp" popularity stems largely from their shows' low-budget production values, the often surrealistic feel of many of the programs, and the uniquely "'70s" style of music and design.
