I used to watch these at the weekend as a kid when TV consisted of 3 channels and used to switch off for a break with only a test card left on the screen.
If I try and show the kids one of these silent black and white movies, they would think the telly was broken! I used feel very sorry for the 'Little Tramp' he never got the girl and tried to elevate himself out of his social situation. I am sure Chaplin was trying to make some sort of comment on depression era society. His character certainly made him a wealthy man!
