The Kid (1921)

Charlie Chaplin's Tramp and Jackie Coogan sit side by side on a doorstep, arms folded the same way, in a publicity still for The Kid. It was Chaplin's first feature as director, and this pairing is why it works: the small boy copies the Tramp's every move, and the two outcasts look like a matched set. The picture sums up the film's mix of comedy and heartbreak before anyone has moved.
