This movie seems to be a biography presented as an autobiography. To build the visual content of Robert Evan's life, multiple sources were used. Obviously real footage of Robert was used along with scenes from his movies. There are also multiple interviews with Robert along with his voice over narration throughout the entire film. On top of all the live action footage, still photographs appear very often. Many times throughout the film, the still photos are slightly animated to add action that follows the narration.
There are many editing techniques used on the still photography used in the movie to add meaning and interest to the sparse content. In some cases, people are cut from their backgrounds and layered on top of one another to show their interaction. Sometimes, color is added to parts of black and white photos. Camera angles change and move around the stills including zoom-ins and panning. Many times also, the camera spirals into and out of photos as they overlap with new images. The film is full of dissolves to express a dream of Robert's past experiences.
At other times throughout the film News articles and photos are animated and come to life as text pops out of its block and scrolls across the page as photos pop from their flat surface and float.
In short, the technical aspects of the film involve taking a small amount of content material and adding interesting animation and overlapping to allow the visual information to be much more interesting.
