A set of pictures taken by the camera man a thousand miles away can be inserted for a few feet in the film, and the audience sees now the clubroom in New York, and now the snows of Alaska and now the tropics, near each other in the same reel.
Moreover the ease with which the scenes are altered allows us not only to hurry on to ever new spots, but to be at the same time in two or three places.

The scenes become intertwined.

We see the soldier on the battlefield, and his beloved one at home, in such steady alternation that we are simultaneously here and there.

We see the man speaking into the telephone in New York and at the same time the woman who receives his message in Washington.

It is no difficulty at all for the photoplay to have the two alternate a score of times in the few minutes of the long distance conversation.
But with the quick change of background the photoartists also gained a rapidity of motion which leaves actual men behind.
