Acording to imdb there are 317 movies which grossed over 200 million @.
Acording to vgchartz there are 119 which sold more than 4 million.
Why 4 million? Becouse if an average game cost 50$ you need to sell 4 million of them to gross 200 million $. (It's not excally right becouse video games prices are mostly lowered after some time and average price is lower than 50 $ in the game lifetime)
Nevertheless it shows that movie industry is bigger and probably few times as vg. I think that Desroko's estimates can be quite close (the video industry also have profits in DVD, TV, etc, which maybe arent as big as cinemas but still are important).
Of course there are some revenues in console systems but they aren't as big.
