I like those actors too, even though neither are surefire promises that a movie is great (seen the Star Wars prequels or Red lately?). More to the point - why do I care about how they interact with Siri? I guess Apple is subtly implying that if you use Siri, you are but one degree of separation from famous/cool people. Cute, but a sad lowering of the bar for a company that once looked for customers that were trying to change the world.
