You know you've made it as an actor when you get turned into a Lego minifigure. I think it used to be when you were turned into any kind of action figure, but, these days, especially after McFarlane Toys came onto the scene in the mid-90s, almost anyone can get turned into an action figure. It ceased to be something difficult to achieve. However, it's still noteworthy to get turned into a minifigure even if minifigures don't look like the actors.
Even more noteworthy? Getting turned into two completely different minifigures. And, yes, okay, this topic completely came out of a conversation with my sons. They have a completely disregard for action figures because, well, all sorts of movies get action figures (or, at least, used to; I suppose that trend has died down somewhat in the last few years), but only the really cool ones get made into Lego.
Of course, this whole conversation started with Harrison Ford.
If you can think of more, let me know!
