Actress Christine White dies at 86 on April 14 at Brinton Woods Nursing Home in Washington, D.C. White was best know for her performance alongside William Shatner on the most notorious episode of the Twilight Zone, airing in 1963. Although Christine White's acting career spanned 20 years, her portrayal as the dutiful wife on the classic, eerie episode will remain her legacy.

Upon hearing the news of his Twilight Zone co-stars's passing, Shatner took to his Twitter.com blog and wrote, "Thoughts go out to the family of my Twilight Zone co-star Christine Lamson White."

"Nightmare at 20,000 Feet" was an episode of The Twilight Zone that still gives audiences chills 50 years after the episode aired.  Christine White played Julia Wilson, Robert Wilson's wife. The great William Shatner played Robert.

Julia Wilson was taking her husband home via flight after a 6 month stay in a sanitarium after a mental breakdown.

 "Honey, you are cured," Mrs. Wilson told her anxious husband as they fastened their seat belts. "That Dr. Martin wouldn't let you fly if you weren't - would he?"

But the flight changed course after some time in the air and veered into "The Twilight Zone."

After seeing a man outside of the plane, Robert tried to convince his wife, who sat calmly with pearls and a face of reassurance, that there was a monster on the wing of the plane.  Of course, because of his past, nobody believed Robert, as the audience anxiously witnesses a monster eating away at the engine.

After Robert's outbursts and screams of a gremlin on the wing, the flight crew must sedate the recently admitted man.  His wife sadly just assumes Robert was released from the asylum before he was fully cured. Robert keeps insisting and gets violent.

Every time Shatner's character tells somebody to come see the man on the wing, the monster disappears. The classic episode ends with the plane's emergency landing because of Wilson's frantic behavior. Robert is put in a straight-jacket and wisked away. The tale ends with the audience gasping at the close up shot of the torn apart, mutilated engine caused by a creature. 

The episode became a classic, still making its mark on pop culture.  It has been remade into a movie, honored in song and spoofed on "Saturday Night Live," "3rd Rock From the Sun" and "The Simpsons."

Ms. White played small roles on "Bonanza," "The Rifleman," "The Untouchables" and "Father Knows Best," but will always be classy Julia Wilson from "Nightmare At 20,000 Feet."
