Is the villain in Ready Player One based on Scientology leader David Miscavige?

My daughter and I saw the movie of Ready Player One last night. I really enjoyed it. One thing that stood out was how the villain of the movie, Nolan Sorrento (played by Ben Mendelsohn), seems to be a dead ringer for Scientology leader David Miscavige, complete with tight-fitting suit. They even have the same brash, gravelly voices (Mendelsohn is Australian and affected a North American accent in the movie). Coincidence?
