Because the ship had been mothballed in the James River Reserve Fleet (on the border of Isle of Wight County and the city of Newport News), it was covered in rust and in disrepair when the filming started. One side of the ship was painted and dressed up for the movie, leaving the other half in poor condition. Hence, only one side of the ship was ever filmed on camera for the movie.
Jamie Lee Curtis has admitted to hating this film, calling it "the worst movie ever made". She added that she lobbied hard to have the director fired and replaced by Steve Miner, with whom she had made Halloween H20: 20 Years Later (1998). However, he wasn't available, as he was working on Dawson's Creek (1998)).
The "Goliath" robot was approximately 9' tall and weighed an estimated 4,000 lbs. The special effects company hired to create Goliath had only three-and-a-half months to produce the robot from the initial drawings to the finished product.
Director John Bruno is a visual effects artist. He was about to start work on the visual effects for Titanic (1997) when the offer came through to direct his first feature.
In an IGN.com interview, Jamie Lee Curtis said the following about Virus (1999): "Rob Reiner, for his 40th birthday, had a bad show business party where everybody brought show business clips. Rob's was playing a hippie on Gomer Pyle, U.S.M.C. (1964) singing 'Blowin' in the Wind'. Virus (1999) is so bad that it's shocking. That would be the all time piece of shit. It's just dreadful. That's the only good reason to be in bad movies. Then when your friends have [bad] movies you can say 'Ahhhh, I've got the best one. I'm bringing Virus (1999).'"
