While filming the climactic fight scene, Mark Hamill was told a punch he'd thrown at Peter Stormare's face didn't look convincing, and was asked to swing "lower and closer." On the next take, Hamill did so and accidentally hit Stormare for real. In a making-of documentary, Hamill is visibly shocked by the accident, which he says split Stormare's lip and caused his face to swell up. In a 2021 interview for Filmtopp, Stormare revealed that one of his teeth was knocked out, forcing him to go to a hospital. He has despised Hamill ever since, calling him "a real idiot" who never apologized: "For me he's a shithead. And he'll always be a shithead. He's in my black book."
The Statoil company paid 500,000 NOK ($USD67,000) for their logo to be displayed for three seconds in the film. See also the goofs entry for this film.
The base took several months to build and nearly 500.000 SEK ($US 60,000) worth of damage was done when it was blown apart.
