(CBS News) Add actor John Malkovich to the list of celebrities enlisted to advertise the iPhone 4S' personal digital assistant Siri.
In the commercial Malkovich asks Siri one-word questions, like to which the software gives presumptive answers. When Malkovich says "evening," Siri responds with the actor's schedule for the night. The actor even asks for a joke, in which Siri responds with: "Two iPhones walk into a bar. I forget the rest."
The "Siri and celebrities" ad campaign kicked off in April, with previous commercials starring "New Girl" actress Zooey Deschanel and actor Samuel L. Jackson.
