Another example would be cultural expectation colouring the reaction. With 'the Eagle' movie, I was amazed to discover US reviews where the American-accented Romans were taken at face value as 'the good guys' because they were clean and had familiar voices, whereas the Britons were depicted as more primitive and clearly 'baddies' (because in Hollywood, the British accents always indicate a bad guy??).

This amazed me particularly, because I thought the depiction of the Romans in that movie showed them as strikingly unsympathetic - indeed, it came across as having a specifically anti-US-imperialism message to me - and in the British cinema where I watched it, people in the audience were cheering on the native British attacks on the Roman fort!

Where your eyes come from really does seem to make a huge difference to what you see with them.
