Not a teacher!
I believe Del Boy already demonstrated the best way not to lean when he fell through the open bar flap, you know what I mean.
I learnt a lot of English by listening to programs on BBC Radio 4 and by watching plenty of comedies on TV. As much fun action movies might be, I think for a learner programs where the focus of attention is on the spoken word are best. Some of my all-time favourite films are "Casablanca" and "12 Angry Men".
