He is drunk and lost his balance.
Timing and Agility of Chaplin are the highlights of this movie
That expression, that fast hand movement, that funny walk
He plays with kids, doing magic for them, enjoying every moment of life.
He creates pain for others casually. He takes his pain casually and moves on. All the while he makes us laugh.
There are many comedy situations like the mischievous child, the fight between the thieves etc. Fun filled entertainer.
Nice commentary on Buster Keaton’s stunt
