Continuity mistake: Near the middle of the film when Joey gets arrested and is being walked down the stairs outside. If you look in the front halfway down the stairs you can see a guy holding a brown box, but when the camera cuts to a face shot of the black man in front of the camera the man holding the box has disappeared, but he should still be visible because he was only half way down the stairs.
Continuity mistake: Before Dade is about to give Fisher Steven´s character a disk, when he was waiting there is a small water pool on the left side. Dade keeps switching places but in the last change the water suddenly shrinks and becomes about 1/4 size of the original.
Laurence Mason's character Lord Nikon was given the name because of his photographic memory.
When MGM/UA set up a website for Hackers, it was like dangling candy in front of a child. Soon after the site was established, it was hacked! A group calling itself the Internet Liberation Front managed to 'doodle' all over the photograph of Hackers stars Angelina Jolie and Jonny Lee Miller, and replaced verbiage, 'this is going to be an entertaining, fun promotional site for a movie,' with 'this is going to be a lame, cheesy promotional site for a movie!' The studio decided to maintain the site during the theatrical run of the movie in its altered form."
Easter egg: When on the menu screen, move the cursor to highlight the Hackers logo. Press enter, and your will be taken to a screen with a choice of four passwords. The correct password is GOD, which one can learn by watching the movie. When the password GOD is selected, you will be taken into a cool short visual of cyberspace.
