What parents need to know

Positive messages

Starfleet is racially and species-integrated, individually quirky but respectful and appreciative of differences. They function as a great team, working together for positive outcomes. Female characters, often on the sidelines or simply love interests, are particularly strong in this mission.

Positive role models

Kirk asks Spock to lie -- which Vulcans can't do, but he's able to "exaggerate" deceptively to achieve their mission. However, overall, Kirk and Spock demonstrate a strong friendship free of prejudice, and are willing to put the needs of others above themselves.


A brief flashback to a spaceship explosion from Star Trek III, but otherwise this is renowned as the Star Trek movie without a single shot fired in anger. One character does suffer a fall, and disastrous storms batter the Earth. Some stock footage of the killing and butchery of whales.

Not applicable

Mr. Spock tries to fit into 20th-century culture by swearing gratuitously ("colorful metaphors," he calls it), played as comedy. Words used include "Goddamn," "hell," "dumbass," and "dips--t." A punk gives Kirk and Spock the finger.


Apple computers get a plug, as well as the Yellow Pages and other 20th-century billboards. Star Trek itself is quite a commodity.

Drinking, drugs, & smoking

Social drinking. Kirk explains Spock's alien ways to a 20th-century heroine by saying he did heavy drugs in the 1960s.

Parents Need to Know

Parents need to know that Star Trek IV: The Voyage Home is the most farcical of the big-screen series. As much comedy as adventure derives from the journey of the Starfleet heroes to 1986 Earth, and the relative rudeness and local color they encounter in San Francisco. While this installment is less scary and violent than most other Star Trek movies, there are instances of comical swearing and drug references. There is also a depiction of the killing of whales. 

What's the story?

Having rescued a returned-from-the-dead Mr. Spock (Leonard Nimoy) and committing multiple offenses against Starfleet in the process, the core crew of the now-destroyed starship Enterprise are in exile on the planet Vulcan at the start of STAR TREK IV: THE VOYAGE HOME. Voting unanimously to return to Earth and face justice, they depart in their captured Klingon ship, only to find their home planet besieged by a bizarre, enigmatic alien space probe that's battering Earth through storms and energy drains. The heroes figure out that the probe is trying to contact humpback whales, described as an intelligent species which, by the 23rd century, have been long extinct, hunted to their doom by greedy humans. Admiral Kirk (William Shatner) orders the crew to time-warp back to the 20th century, where humpback whales can be found.

Is it any good?


This movie successfully captured the same lighthearted spirit of some of the classic 1960s TV episodes. The bulk of the fun of Star Trek IV: The Voyage Home -- and it is fun, much of the time, played for breezy laughs, despite the mortal peril for the Earth -- centers on the super-competent 23rd-century visitors' awkwardness fitting into 1986 Earth society and dealing with money, rude people, profanity, exact bus fare, and more.

The cast has seldom been more charming (and that's saying a lot), and there's a running undercurrent about Spock gradually reconnecting with his shipmates and learning to balance logic with emotion. Sure, the special effects are good too (note the use of early CGI to simulate the time warp), but it's the beloved characterizations that set it apart from the vast majority of screen science-fiction that's all about the gadgets, rockets, aliens, and monster costumes.

Families can talk about...

  • Families can talk about Star Trek IV: The Voyage Home's emphasis on comedy, and the culture-shock of the future space travelers in (more or less) present-day Earth society. What aspects of this world do you think would bewilder visitors from tomorrow?

  • Is there an eco-friendly message to this film? What do the heroes do to protect the Earth in the recent past to save the distant future?

  • Which elements of the Star Trek universe are possible and which are purely science fiction? Is there any technology that they have in Starfleet that is similar to something that exists today?

Positive Messages

Star Trek: The Voyage Home is a movie with a cause. The main message is that we depend on other species, and by coexisting with them we gain security. One of your main concerns as a parent is cursing (very frequently in some parts). Otherwise, it has lots of humor, and is different from any other Star Trek movie, and is one of my favorites.

This star trek movie is like almost all of the other star treks. The only main Difference is the the social behavier because there is alot more swearing. The message is also very interesting because a probe is sent to earth to see if there are any whales on the planet. But there aren't any, so Kirk goes back in time to get a whale. Kirk gets the whale for two reasons. First all the have been hunted to extiction, this is the message: save the whales, and to save the the planet.
