I may also be looking for impressionists for characters which have been voiced already in the games. 

As I’m very much opposed to the use of AI in replacing human creativity I would much prefer not to resort to it. I will be looking for anyone who may be able to perform impressions of the following characters/voice actors/actresses: GYSGT Buck (Nathan Fillion), CPT Dare (Tricia Helfer), LCPL Romeo (Nolan North), PVT Mickey (Alan Tudyk), CPL Dutch (Adam Baldwin), SGTMJR Avery Johnson (David Scully), CMDR Sarah Palmer (Jennifer Hale), Sadie Endesha (Masasa Moyo), Vergil/The Superintendent AI (Joseph Staten), and the possibility of Covenant Enemy Voices; ie. Brutes, Elites, Grunts, Jackals etc. I intend to be clever with my filmmaking, placing these enemies out of frame to avoid the use of CGI, while still having them present. That being said, Buck, Romeo, Mickey, Dutch, and Palmer are present during Captain Ingridsons section in New Blood, without their lines it may be very difficult to include that scene (which may force me to resort to ai use, very much would like to avoid this). Dare, Johnson, Sadie, and Vergil may be very useful roles for expanding my films link to Vergil; the Huragok which provides the coordinates for The Rookie to hunt down in this film. and lastly, Vergils voice along with the Covenant enemies will be highly useful to include throughout the second and third acts of the film, the enemies as a foil for The Rookie to stealthily avoid and Vergil as a guiding voice over comms for Rook to follow. You may opt to choose your own lines which have already been said by these characters, or I have provided a number of samples which could work as well.
