I love the kid who is hamming it up at the bottom of the frame. I've been a photographer/videographer for my entire professional career and have run into this kid many, many times. Adults exhibit this behavior too but it is usually much more moderated.
This kid had to know what a camera was, which end was filming (some early film cameras appeared to be simple boxes), and wanted to make his mark on the final product.
Some guy smacks the kid with a light left hook at about 1:14.
It’s crazy to me watching this and thinking that if that kid lived to 100 he would’ve died 30+ years ago. That unknown child will be forever captured on this film.
Every time I watch old films with children in them I always think about how they’ve been dead, hopefully of old age, for a long time already.
