Factual error: When Banderas is in the hotel room with the four dead guys, he realizes that Stallone is in the other room. When Banderas looks at the hotel TV screen, it displays the in-room guest service welcome page: "Welcome to Marriot's In-Room Guest Services". The hotel name is misspelled, while the spelling in the logo above it is correct.
Factual error: The file sizes shown copied to the disk add up to over 700mb - more than would fit onto a CD, let alone a 1.44mb floppy disk. It's been claimed the disk is a SuperDisk or a Zip disk, but SuperDisk wasn't available until after this film was made, and Zip disks look noticeably different. Regardless, neither of those formats could hold anything like 700mb either.
