Plucked from obscurity, clean-cut Kyle MacLachlan became a movie star overnight when he landed the lead in the epic space opera "Dune" (1984), but the film's disastrous critical reception nearly consigned him to the role of "has been" just as quickly. Luckily for MacLachlan, he had a guardian angel in David Lynch, the visionary director who had cast him in the adaptation of the classic science fiction novel. Lynch would give MacLachlan the starring role in his next film, "Blue Velvet" (1986) and a lead role on the surrealistic television series "Twin Peaks" (ABC, 1990-91). The former would eventually be regarded as a cinematic masterpiece, while the latter became an instant sensation during its first season. Big box office success, however, continued to elude MacLachlan with overlooked vehicles like the sci-fi thriller "The Hidden" (1987) and Oliver Stone's facile Jim Morrison biopic "The Doors" (1991), as well as starring in the laughing stock that was "Showgirls" (1995), which later developed a rabid cult following. MacLachlan would make a modest return to notoriety on television with recurring parts as the wealthy, impotent husband of Charlotte York on "Sex in the City" (HBO, 1998-2004), and later on the guilty pleasure "Desperate Housewives" (ABC, 2004- ). And while the endearingly stiff MacLachlan became known as a respected working actor, continuing to appear in film and episodic television, there remained the lingering impression of a promising career unfulfilled after such an auspicious beginning under the tutelage of David Lynch.
