10. Q Is Reading Cue Cards While Talking To Bond - GoldenEye
Firstly, all respect in the world to the late, great Desmond Llewelyn - an iconic and inestimable icon of 007 lore who played Q in 17 Bond films across more than 35 years.
However, keen-eyed viewers who pay attention to his appearance in GoldenEye will notice that the actor is very clearly reading from cue cards placed around the set.
This is most noticeable when Q and Bond (Pierce Brosnan) are stood by a BT telephone box as Q explains a gadget to him.
It's clear that Llewelyn is actually looking over Brosnan's shoulder while speaking, his eyes moving from left to right as he reads the technobabble dialogue from a cue card or similar device behind the actor.
That's no criticism of Llewelyn at all - hell, acting giants like Brando used cue cards - but simply an observation that's sure to distract the hell out of fans on repeat viewings. So, erm, sorry about that.
