Leprechaun 4 in space

Bad sci-fi effort (is there a good kind?) where the little monster is hiding out with a young woman on a planet. A battle crew arrive and kill the leprechaun but he can regenerate and appears on the spaceship. Mayhem ensues with lots of bad dialogue and 'homages' to Alien, Dr Who, and other movies. Easily the worst one so far watched in the series and the only Irish reference is the singing of Danny boy. One good scene was with the green lightsabre!
