Didn’t the same thing happen in Superman III? I seem to recall a computer display is shown with various advanced-looking outputs and then they also run a LIST command, which lists a BASIC (or maybe COMAL) program written to… display various advanced-looking outputs. Using the PRINT statement. Followed by many individual lines of PRINT "" to make the screen clear.
Iron Man (2008) shows that Iron Man boots with the Mozilla JavaScript documentation. It seems to favor RegExp. Maybe that was shoddy movie research, maybe we should be glad that Iron Man does not run on W3Schools tutorials, maybe Jeff Atwood is right when he said: any application that can be written in JavaScript, will eventually be written in JavaScript.
