Most people know that actor Patrick Warburton is part of the queue at Disney California Adventure's Soarin' attraction, going over the rules for guests before they take flight.  Many but probably a lesser number of people realize that he's also in the line of another ride across the Esplanade, in Disneyland Park.  That ride would be Star Tours, and less obviously, Patrick Warburton voices droid G2-4T, a scanner who checks security but mostly tells people to move along before they arrive at the Star Cruiser gates.  He's silly and rambling, and his voice is modulated, but it's still unmistakable.  It's a fun little part of this regularly-evolving attraction!
