We have already mentioned works of Blackton. He created one of the first animated films. However, he started using animation even earlier. In The Enchanted Drawing (1900)
animation is used as a supplement. We see a man who sketches the portrait of a gentleman on an easel. Then the cartoonist draws a bottle of wine and a goblet. One of the reasons why this film cannot be considered as an animation film is that the cartoonist interacts with a drawn picture. He "removes" real wine from the picture and drinks it. Then he takes a cylinder of the drawn gentleman.
Another work of Blackton's, The Haunted Hotel (1907)
, was a huge success in Europe. Here Blackton used stop-motion animation to create the atmosphere of a haunted place: the bread was sliced, but nobody held a knife. Blackton's works weren't really unique, but it is thanks to them that animation started to prosper as a distinct genre.
