Flashbacks without exposition are pretty good but I saw a really good example in the movie Mute recently.
The movie is about some German Amish dude that got his vocal cords damaged in an accident but in the background of a scene for about 5 seconds of a trial and apparently various background graffiti and posters set up in the background scenes of Mute referencing Moon, both of which have the same director. Mute is a futuristic blade runner style dystopian future, and moon has lithium 3 harvesters, thats like the setting of the movie Moon, there are a lot of these harvesters.
The 5 second video of the trial connects the two and establishes that most of the electricity in Mute comes from Lithium3, not the element lithium which is number 3 but the nuclear material sometimes refered to as heavy lithium, see heavy water for reference I'm probably fucking up the description but you get the idea.
so summarizing, that's 5 seconds of focused attention, the trial, to build the world of Mute massively, not to mention the less noticeable posters and shit that I didn't even catch because I didn't even catch the trial connection until after the movie.
Now if you want to make some more obvious world building you can look at the first matrix movie, not that the series isn't full of shitty exposition but the scenes where he gets a phone call that the agents are coming for him, pardon the shit video quality, establishes the agents as a force to be feared without even having to talk about what they are, they throw in a little explanation later but a lot more is established in the minds of the viewer WITHOUT needless dialogue and exposition.
