The indirect inspiration for the Austin Powers films !!! with blatant innuendo and overt smoking and over the top costumes !!!! But I really only purchased it for the Wrecking Crew which showcased Bruce Lee fight choreography but he is billed as the karate advisor. Also had Chuck Norris as a henchman . Some other notable names in martial arts were used as stuntmen ~ Ed Parker , Joe Lewis and Mike Stone . Didn't notice how dark Dean Martin actually is until I watched these films.
Being a fan of classic 60s spy movies and the "mod" style that went with a lot of them, these movies are must haves. The fun that Dean Martin obviously had making them is contagious. They're a blast.
