Halo 2 storyboards
From Halopedia, the Halo wiki
When Lee Wilson started the storyboards, it was clear to him that the script was not ready for shooting boards due to the numerous script revisions at Bungie. This lead to Lee boarding up the entire cinematic script two to three times. What he opted to do was present the boards in a hybrid storyboard/comic panel style, drawing them in pen to "remove the temptation of erasing and redrawing them until they looked good to me". These boards were for simple communication, not to be displayed on a wall.
E3 2003 boards
These boards were also drawn by Lee R. Wilson. These were for the Halo 2 E3 Demo.
