T800 - The Terminator (1984)
In what’s perhaps his defining role, Schwarzenegger stole the show as the titular tin man in the opening salvo of the Terminator saga. Cold, calculating and methodical, he cuts a bloody swathe through the movie as the mechanical menace sent back from the future to off Sarah Connor. The T800 is perhaps one of the best villains to ever grace the silver screen, and much of that is down to Arnie’s pitch perfect performance. Sadly it’s the only time he’s ever played the villain, but boy did he do it well.
