I remember taking my cousin to see the OT triple bill (he had only seen Jedi and wasn't paying much attention first time on account of him being so young and hyperactive).

When Episode IV A New Hope came up he prodded me in the ribs and said he had only seen the third one.

When ESB started with "A long time ago..." he thought they put the fourth one back on again.

His verdict after seeing all three was he liked Jedi the most and Empire the least (because the Falcon kept breaking down).

When I showed them to an Indian friend of mine (who grew up in a small village and had seen hardly any films) he liked them but he didn't know what all the red lines were.

He also thought that Blade Runner was set in contemporary America and was amazed that they had flying police cars in the USA.

Showing him The Rocky Horror Picture Show was a giggle.
