Ds1 has just sat and watched My Fair Lady all the way through with me. Given his phobia of 'movies' this is an important step forward, being the third film we have been able to get him to watch so far this year. (First one was a Pokemon film, second Puss in Boots - which was a biggie, being a big modern feature film - and now this one.)
But .... blimey, the questions!
MFL is one of my favourite all time films and he kept up a pretty much constant barrage of questions regarding the interaction between characters, why they did and said things etc. Most recent ones being "Why is he signing about getting married if he doesn't want to get married? Why does he want to get to the church on time if he doesn't want to get married?" "Why is he celebrating if he's sad to be getting married?" .... AAARRRGH!
He's enjoyed the songs, but been totally unable to get the social aspects of the story. Funnily enough, he doesn't seem to thing Henry Higgings is rude or insensitive at all! 
We have bought Star Wars the Original Trilogy to take on holiday with us, as he's desperate to watch them so he can talk about them with his friends at school. Not sure if he'll manage to watch them, but if he does I'm now wondering whether the rest of us will be able to hear a word of it through his questions.
