Basic Instinct (1992)
Wayne Knight (John Correli), who hilariously played Newman the mailman on "Seinfeld," gave the priceless look of amazement as he gazed at Sharon Stone in the infamous leg-crossing scene.
Daniel von Bargen (Lieutenant Nilsen), Michael Douglas's superior officer, played George Costanza's boss, the head of Kruger Industrial Smoothing, on several "Seinfeld" episodes.
Stephen Tobolowsky (Dr. Lamott), one of the psychiatrists evaluating Douglas's character, played the new-age wacko Tor who tried to cure George's tonsillitis.
Bradford English, the Campus Policeman questioned by Douglas, played a Cop on the episode in which Jerry's apartment is robbed.
James Rebhorn (Dr. McElwaine), another shrink, was the prosecutor in the final episode of the show.
