10 Sci-Fi Movie Mistakes You Can’t Unsee

10. Terminator 2: Judgement Day - Hand Switch

Arnold Schwarzenegger's entrance in James Cameron's Terminator sequel Judgement Day has become the stuff of movie legend... and rightfully so.

A completely naked T-800 enters a bar and demands a biker's 'clothes, boots and (his) motorcycle' . After the fool refuses the hulking figure, it decides to take them by force.

It's an absolute joy seeing Arnie swat away civilians with ease and its quite easy to get wrapped up in the compelling chaos going down in the scene. However, there is one moment which becomes slightly jarring as soon as you open your eyes to the mistake.

When the T-800 disarms one of the goons, the machine can be seen grabbing the guy's knife with his left hand and disabling him with his right. Yet, in the next shot, the robot is seen plunging the knife into his victims back using his right hand, with his left now being used to keep the poor lad on the pool table.

It's certainly an easily missed moment of dodgy continuity, but thankfully it takes nothing away from the no-nonsense arse kicking on show throughout this epic introduction.
