For HD universe you can grab mostly all voice actors, because they are look like these game characters (peds sometimes references to some US pop stars). For GTA IV you can grab voice actors OR references like Niko Bellic. 3d shots can be used too, of course, but if only there is no refs or voice actors which resembles these characters.
Just to answer some of the common questions: All of the footage comes from the Kinolibrary archives. I wanted to make the video longer, but I was restricted by what was available in the archives that also matched locations in the game, and were filmed around the time of the games setting (I kept it to late 80s/early 90s). The music is an AI generated track made using Udio AI, so this is the only place you'll find it.
