The scene where it shows just Blazes eyes (when the Bike starts taking off), that was a direct reference to the beginning of the Host-to-GR transformation in the comics.
I saw it in the Marvel Essentials Vol 1 (or was it Vol 2), this frame was also used in the Dan Ketch series.
Another reference was when he crashed down from his free fall to the ground off a building, this was done NUMEROUS times in the 2nd run of the comics. There was a great one done by Salvador LaRocca in one of the first issues scribed by Ivan Velez Jr.
The scene where GR enters the graveyard is a good reference to Cypress Hills Cemetary and the 1st place GR goes for solace in Howard Mackie's run.
