Watch Star Trek IV: The Voyage Home Online

Star Trek IV: The Voyage Home (Paramount Pictures, 1986) is the fourth feature film based on the Star Trek science fiction television series. Leonard Nimoy directed as well as starred in The Voyage Home, which earned four Academy Award nominations, for Best Cinematography, Best Effects, Best Music and Best Sound. The original music score was composed by Leonard Rosenman, reusing some material from his earlier score to Ralph Bakshi's animated The Lord of the Rings.

The movie begins with a dedication from "the cast and crew of Star Trek" to the memory of the seven astronauts who were killed in the Space Shuttle Challenger disaster on January 28, 1986 (between the previous film and this one).

The film was a critical and commercial success. It grossed $109,713,132 in the U.S. and $133,000,000 worldwide, against a $27,000,000 budget. Of the first ten films, it sold the second-most tickets and was the second most profitable movie in the series adjusted for 2007 inflation (behind The Motion Picture). On the Special Edition DVD of the film, Leonard Nimoy says that this was the most well-received of all the Star Trek films made to date. Producer Ralph Winter also added that this film did very well as it was liked by both fans and non-fans of the Star Trek phenomenon.

USA Today gave a positive review, declaring "Kirk and company turn into the most uproarious out-of-towners to hit the Bay area since the Democrats in 1984," and felt the lack of special effects allowed the actors to "prove themselves more capable actors than ever before." Janet Maslin of The New York Times noted The Voyage Home "has done a great deal to ensure the series' longevity".

When released in Europe and South America, the film was given the title The Voyage Home: Star Trek IV and had a prologue narrated by Shatner and scored by Leonard Rosenman reviewing the events of the previous two films. It was included on the European, Asian and South American VHS release.

The Voyage Home was the first Star Trek film shown in the Soviet Union. It was screened by the World Wildlife Fund on June 26, 1987 in Moscow to celebrate a ban on whaling. Nimoy and Bennett attended the screening; Nimoy had completed filming Three Men and a Baby the day before and enjoyed visiting Russia, where his ancestors came from. Bennett was amazed the film got the same laughs as it did with an American audience. He said "the single most rewarding moment of my Star Trek life" was when the Moscow audience applauded at McCoy's line at the film's end, "The bureaucratic mentality is the only constant in the universe. We'll get a freighter," which was a clear "messenger of what was to come".
