Star Trek IV: The Voyage Home is endlessly enjoyable, but upon rewatch, I’m taken aback by one particular insult hurled at Commander Pavel Chekov (Walter Koenig). Directed by Leonard Nimoy, Star Trek IV was a crowd-pleasing blockbuster that became a crossover hit enjoyed by mainstream audiences in 1986. In Star Trek IV, Admiral James T. Kirk (William Shatner) and the former crew of the USS Enterprise time-travel to 20th-century San Francisco to bring two humpback whales back to the future.
