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: USMC (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).'"
Because of the ship being mothballed in the James River Reserve Fleet, on the border of Isle of Wight County and city of Newport News, the ship was covered in rust and disrepair when the filming started.
