If sci-fi fans knew that the code that reboots a space station in the movie Elysium is actually taken from an Intel processor manual, they might be less than impressed.
And Iron Man's exploits seem slightly disappointing when you know that code in his visor is for a Lego computer.
Producers take chunks of coding from manuals, websites and even Wikipedia, John Graham-Cumming told the BBC.
"I was watching Elysium and this guy had to write a programme," he said. "What appeared on screen was clearly the assembly language for an Intel x86 processor - basically any standard Intel chip."
Really, who's the technical advisor...Lego Man?
