Hollywood fears the release of Grand Theft Auto IV tomorrow. And they should. The somewhat controversial game is set for $1 billion in sales the first week. Yes, that’s a ‘b,’ no typo. It will instantly make GTA the biggest entertainment franchise ever.

The game does well with young males and that’s the same target audience a movie like ‘Iron Man’ has. Last year, film Executives blamed the ‘Halo 3′ launch for the relatively low opening of ‘The Heartbreak Kid’ with Ben Stiller. And with the amount of blockbusters this summer, Hollywood doesn’t seem to be waiting for another game like that to compete for their money.

In a recent Financial Times article, Electronic Arts CEO John Riccitiello said that there’s “more interest today from Hollywood to make movies out of our games than there is interest in our industry to make games out of their movies. There’s a big reset happening now. The rate of change in this industry is massive.“

So this is why Spielberg is making games nowadays.
