... but I also think today's megastars-- The Rock, Ryan Reynolds, etc.-- are even more risk averse than guys like Will Smith are. Like, they won't even bother trying to do the accent in a biopic and shit, lol.

So while I think you're more or less on the money, the window for "how safe superstars play it" continues to shift safer and safer to a point where Smith doesn't feel nearly as safe as many "stars" in the current class. For whatever that means.
