Apple taps Martin Scorsese for new Siri ad

Apple's latest Siri ad features legendary Martin Scorsese, director of some of the most influential movies of our time including Mean Streets, Taxi Driver, Raging Bull, Goodfellas and The Departed.

Apple has expanded its line of television ads promoting Siri, the voice-enabled assistant for iOS, with a new spot featuring director Martin Scorsese. Apple has previously released Siri commercials featuring Samuel L. JacksonJohn Malkovich, and Zooey Deschanel.

Scorsese must be an Apple fan, I can't imagine him doing a television commerical for the money. 

Which celebrity should Apple tap for its next Siri ad?
