The use of flash-back structures continued to develop in this period, and the usual way of entering and leaving a flash-back was through a dissolve, and this was in fact the principal use at this time for this device. The Vitagraph company's The Man That Might Have Been (William Humphrey, 1914), is even more complex, with a series of reveries and flash-backs that contrast the protagonist's real passage through life with what might have been, if his son had not died. In this film dissolves are used both to enter and leave the flash-backs, and also the wish-dreams, and also for a time-lapse inside a reverie at one point. But fades are also used for these purposes in this and other films of the period, and flashback transitions are also done with irising in other films, and even straight cuts. During World War I the use of flashbacks occurred in films from all the major European film-making countries as well, from Italy (Tigre reale) to Denmark (Evangeliemandens Liv) to Russia (Grezy and Posle smerti), where it arrived in 1915.
As the years moved on a sudden decline in the use of long flash-back sequences set in around 1917, but on the other hand the use of a transition to and from a brief single shot memory scene remained quite common in American films. However, there could still be an even more complex flash-back construction in American films in the case ofW.S. Van Dyke'sThe Lady of the Dugout (1918). This film has a story that happened long before which is narrated by one character in the framing scene, and initially accompanied by his narrating dialogue in intertitles, though after a while this stops, and the intertitles then convey the dialogue occurring within the flashback. Inside this main flashback there develops cross-cutting to another story, happening at the same time, and at first apparently unconnected with it, though the connection eventually appears. Next, inside this first flashback, the Lady of the title narrates another story, presented in flashback form, but with cutaways inside it back to events occurring in the time frame in which she is doing her narrating. Actually, all this is fairly easy to follow while watching the film, in part because what happens in all these strings of action is relatively simple.
