Leprechaun 4: In Space is a 1997 American science fiction black comedy slasher film directed by Brian Trenchard-Smith and written by Dennis Pratt. Warwick Davis stars as the titular leprechaun, who terrorizes a Marine crew aboard a spaceship in order to retrieve a princess he intends to wed. The film is the fourth installment in the Leprechaun series, preceded by Leprechaun 3 (1995) and followed by Leprechaun in the Hood (2000). It received largely negative reviews. Plot In 2096, on a remote planet, the Leprechaun courts an alien princess named Zarina, in a nefarious plot to become king of her home planet. The two agree to marry, with each partner secretly planning to kill the other after the wedding night in order to enjoy the marriage benefits (a peerage for the Leprechaun, the Leprechaun's gold and jewels for the princess) undisturbed. A platoon of space marines arrive on the planet and kill the Leprechaun for interfering with mining operations. Lucky tries to steal gold but gets killed by the leprechaun's lightsaber. A grenade explodes and kills the leprechaun. Gloating over the victory, one of the marines, Kowalski, urinates on the Leprechaun's body. Unbeknownst to Kowalski, the Leprechaun's spirit travels up his urine stream and into his penis, where his presence manifests as gonorrhea. The marines return to their ship with the injured Zarina, whom they plan to return to her homeworld in order to establish positive diplomatic relations. The ship's commander, the cyborg Dr. Mittenhand, explains his plans to use Zarina's regenerative DNA to recreate his own body, which was mutilated in a failed experiment. Elsewhere on the ship, the Leprechaun violently emerges from Kowalski's penis after he is aroused during a sexual act. The marines hunt the Leprechaun, who outsmarts them and kills most of the crew in gruesome and absurd ways. While pursuing Zarina, the Leprechaun injects Mittenhand with a mixture of Zarina's DNA and the remains of a blended scorpion and tarantula, before initiating the ship's self-destruct mechanism. A surviving marine, Sticks, rushes to the bridge to defuse the self-destruct but is stopped by a password prompt. Mittenhand—now a grotesque monster calling himself "Mittenspider"—entangles Sticks in a giant web. Meanwhile, the other survivors confront the Leprechaun in the cargo bay, where they inadvertently cause him to transform into a giant after shooting him with Dr. Mittenhand's experimental growth ray. The ship's biological officer, Tina Reeves, escapes to
