Grand Theft Auto IV is a multi-hundred-million-dollar blockbuster, so Michael Hollick (film credits: four episodes of various Law & Order franchises in eight years), the unknown actor who did the line readings for the lead character
thinks that he should get royalties, rather than the per-diem (which added up to over $100k). Frankly, even $100k sounds remarkably generous, given that no one buys Grand Theft Auto IV to hear Hollick's voice, and there were dozens of other unemployed actors (including
Deputy Sacks from Veronica Mars Season 1 (via
ALOTT5MA))
looking for work.
