According to the DVD commentary of the film, Star Trek II: The Wrath of Khan, actors Leonard Nimoy and Kirstie Alley, portraying Spock and Saavik respectively, spoke their lines in English, and later dubbed in alien dialogue ( at least partially designed by linguist Marc Okrand ) that corresponded with the movements of their mouths in the scene.

Nimoy had not intended to join the cast of Star Trek II: The Wrath of Khan, but was enticed back with the promise that his character would be given a dramatic death scene.

Faced with producing a new film in time for Star Treks 25th anniversary, Flinn and Meyer, the director of Star Trek II: The Wrath of Khan, wrote a script based on a suggestion from Leonard Nimoy about what would happen if " the wall came down in space ", touching on the contemporary events of the Cold War.

Nimoy's hiring of Meyer was not only beneficial because Meyer knew the material and could write fast ( having produced The Wrath of Khans screenplay in twelve days ), but if Meyer was to direct it would offset any acrimony from Shatner, whose ire would have been aroused if Nimoy returned to direct his third Star Trek feature after The Search for Spock and The Voyage Home.

Upon seeing The Wrath of Khan, Leonard Nimoy became " excited " about playing Spock again.

Bennett and Nimoy used the open thread of Spock mind melding with McCoy at the end of The Wrath of Khan as a way to explain Spock's restoration.

At the end of Star Trek II: The Wrath of Khan, Leonard Nimoy reads a version of the quotation that adds the word " continuing " between " the " and " voyages ", replaces the words " its five-year " with " her on-going ", and adds the word " forms " after " life ": Space ... the Final Frontier.

At the end of the Star Trek motion picture released in 2009, Nimoy reads a revised version of his quotation from Star Trek II: The Wrath of Khan that segues from the original series ' opening to the phrase " her ongoing mission " in place of " its five-year mission ", and closes with the Next Generations gender-neutral version: Space ... the Final Frontier.

Spock ( Leonard Nimoy ) commands the Enterprise, serving as a training ship, at the beginning of Star Trek II: The Wrath of Khan ( 1982 ), but Kirk assumes command when the ship investigates problems with Project Genesis.

As the half-Vulcan, half-human Spock — a role he chose instead of one on the soap opera Peyton Place — Nimoy became a star, and the press predicted that he would " have his choice of movies or television series.

Nimoy would go on to direct the second most successful film ( critically and financially ) in the franchise after the 2009 Star Trek film, Star Trek IV: The Voyage Home ( 1986 ), and Three Men and a Baby, the highest grossing film of 1987, made him a star director.

Nimoy also played the Mermelstein role and believes: " If every project brought me the same sense of fulfillment that Never Forget did, I would truly be in paradise.

Nimoy was given casting approval over who would play the young Spock in the newest film.

Nimoy had much input into how Spock would act in certain situations, and conversely, Nimoy's contemplation of how Spock acted gave him cause to think about things in a way that he never would have thought if he had not portrayed the character.

However, Nimoy would express relief in later interviews and appearances that when he explained the concept to William Shatner, he understood it immediately, and Nimoy credits Shatner's reaction to the nerve pinch in the episode as what really sold it.

After DeForest Kelley in 1964 stated his non-interest in playing the role, Roddenberry cast Nimoy because he knew him from a guest appearance in his pilot The Lieutenant ; after Roddenberry saw Nimoy's thin face and sharp features, no other actors were considered-Kelley, on the other hand, would later be cast as Dr. McCoy, the highly emotional human who became Spock's frequent foil.

Had Nimoy turned down the role, Roddenberry would have approached Martin Landau.

Like other Star Trek actors Kelley received little of the enormous profits that the franchise generated for Paramount, until Nimoy, as executive producer, helped arrange for Kelley to be paid $ 1 million for Star Trek VI ( 1991 ) which would eventually be his final live action film appearance.

The Scott character, as conceived, would have been a semi-regular, but with fellow cast members Leonard Nimoy ( Spock ) and DeForest Kelley ( Dr. McCoy ), was elevated in importance to leads alongside William Shatner's Captain James T. Kirk.

Nimoy hit upon the idea of humpback whales after talking with a friend — their song added mystery to the story, and their size added logistical challenges the heroes would have to overcome.

Nimoy and Murphy acknowledged his part would attract non-Star Trek fans to the franchise following the rising popularity of Murphy, but it also meant the film might be ridiculed.

He would write a few pages, show it to Nimoy and Bennett for consultation, and return to his office to write some more.

Nimoy debated whether the crew should change costumes, but after seeing how people in San Francisco are dressed, he decided they would still fit in.

Shatner, Nimoy, and Kelley's salaries were cut with the understanding that they would share in box office profits.

Designer Michael Okuda had finished a schematic of the Enterprises decks when Nimoy pointed out he had misspelled " reclamation "; while Okuda was fairly certain no one else would notice the single spelling error on the print, he had to fix it.

The cast was split on the possibility of a sequel ; Shatner, Nimoy and Kelley said that the film would be their last, while the supporting cast strongly lobbied for another film.

Landau's replacement is former Star Trek actor Leonard Nimoy, while a permanent replacement for Bain would not be chosen until the 1970 – 71 season.

Leonard Nimoy refused to sign up to lend his voice to the series unless Nichelle Nichols and George Takei were added to the cast — claiming that Sulu and Uhura were of importance as they were proof of the ethnic diversity of the 23rd century and should not be recast.

When a new Star Trek series was planned in the late 1970s, Nimoy was to be in only two out of eleven episodes, but when the show was elevated to a feature film, he agreed to reprise his role.

Nimoy returned as Dr. Bell in the autumn for an extended arc, and according to Roberto Orci, co-creator of Fringe, Bell will be " the beginning of the answers to even bigger questions.

Spock's death was intended to be irrevocable, but Nimoy had such a positive experience during filming that he asked if he could find a way for Spock to return in a later film.

During this scene, Nimoy reads the famous " These are the voyages " monologue — which, till then, was used only to begin Star Trek stories, thus implying Spock's " story " might not be over.

Nimoy was invited to be guest of honor at the March 1967 National Space Club dinner, and to take an extensive tour of the Goddard Space Flight Center in Greenbelt, MD.

Despite Shatner's doubts, Nimoy and Bennett selected a time travel story in which the Enterprise crew encounters a problem that could only be fixed by something only available in the present day ( the Star Trek characters ' past ).

Nimoy intended the crew's introduction to the streets of San Francisco to be accompanied by something reminiscent of George Gershwin, but Rosenman changed the director's mind, and the scene was scored with a contemporary jazz fusion piece by Yellowjackets.

In contrast, Nimoy and Shatner's memoirs report that after the screening he called his lawyer and demanded a quarter of the scenes be cut ; the producers refused, and within 48 hours he was dead.

" Studio chief Michael Eisner was reluctant to hire Nimoy because he mistakenly believed that the actor hated Star Trek and had demanded in his contract that Spock be killed.

Nimoy wanted The Search for Spock to be " operatic " in scope ; " I wanted the emotions to be very large, very broad, life and death themes [...] and the of the film and everything about it derives everything from sizeable characters playing out a large story on a large canvas ," he said.

Although he sometimes commands the ship when both Captain Kirk and first officer Spock ( Leonard Nimoy ) are off the ship ( as third senior officer ), Scotty asserts in the TNG episode " Relics " that he " never wanted to be anything else but an engineer ".

The press predicted that Nimoy would be a star after the show ended, however, and James Doohan expected that appearing on an NBC series would help his post-Star Trek career.

" Of the characterizations, she adds, " Nimoy appears to be having a wonderful time playing a relaxed, calculating villain, and Shatner portrays Sargon in an amplified booming benevolent voice that makes a nifty contrast to his would-be-Kennedyesque speechifying, expounding on the values that sent humans to the stars.

In an interview with Sondra Marshak, published in Star Trek Lives ( written by Jacqueline Lichtenberg, Sondra Marshak and Joan Winston ), Leonard Nimoy explained that when he complained about the script to producer Fred Freiberger, Freiberger said, " This script is going to be what ' Miri ' should have been.
