This is supposed to be the "first staged narrative in film", although it is really better described as one of the "actualities" that Edison's films were known as, and what ultimately, about 20 years later, was their downfall. Actualities really had no story, they were just glimpses into normal life, and sometimes the weird and fanciful, but none really had a story.
Apparently the guy in the middle is an actual blacksmith and the two assistants are actors. Together they hammer on a heated rod placed on an anvil. Afterwards, the three share a bottle of beer. Both actors had long lives. One lived from 1850-1931. The other, Charles Kayser, lived from 1878-1966, which would have made him only fifteen when this film was made. So he would have lived to see movies grow from these actualities, to features, the coming of sound, then TV, then even color TV.
