This 60 year old Vietnamese guy learned English by watching movies in order to sell postcards in Saigon for his family. No teacher, no classes, self-taught.

Wow. Impressive. He definitely sounded a lot more fluent than most of my colleagues… 
Impressive video! He speaks naturally like American movie stars. No teacher, no classes, no LingQ! (grin) I should stick to watching movies.
Thanks.
