John Malkovich is the latest celebrity to shill for Apple by having a charming conversation with the iPhone’s Siri.

But Malkovich being Malkovich, his conversation is deeply philosophical. He doesn’t even ask Siri a question, really, he just mutters the word, “Life,” and then gets a succinct yet somehow all-encompassing answer regarding its meaning, via his handy mobile device.

“Try and be nice to people, avoid eating fat, read a good book every now and then, get some walking in and try to live together in peace and harmony with people of all creeds and nations,” Siri says.

There’s another Malkovich spot in which he makes dinner plans using his iPhone and laughs thoroughly unconvincingly at Siri’s wretched attempt at humor. But this one (see below) is better. It now ranks in first place among celebrity Siri commercials. In second: Samuel L. Jackson’s search for an organic market and refusal to eat “hot-spacho.” In last, obviously: Zooey Deschanel’s rainy day hunt for tomato soup. (Why does she seem so suspicious when she looks out the window? What is she hiding?)

Anyway, I look forward to future Malkovich Siri commercials, including, hopefully, one in which he seeks directions to Floor 7 1/2.
