How NCIS' Mark Harmon Nearly Replaced Don Johnson In Miami Vice
Following a pay dispute on Miami Vice, Don Johnson came close to being replaced by NCIS' Mark Harmon. NBC's Miami Vice debuted in 1984 and followed vice cops Crockett (Don Johnson) and Tubbs (Philip Michael Thomas). What set the show apart from other police series of the era was its glossy, cinematic sheen and fashion, in addition to its MTV-style pacing and use of music. Miami Vice was simply unlike any other show on television at the time, which propelled it to become a major success.
