We hear a lot about Celebrities lending their voices to animated films and television commercials. In fact, it's become so popular to use celebrities for major advertisers, I usually play a game when I'm watching TV at night, trying to guess which star voicing what product.
A few years back, Robert De Niro did a recording for a television promo centered around the Tribeca Film Festival, an event that he co-founded a dozen years ago, which starts later this month in New York. De Niro is known for his shyness and sometimes awkward interviews. It's apparent from this recording that he didn't enjoy the suggestions the director was making, or he was just in a bad mood. Either way, I could listen to outtakes like this all day. (Upon listening to this more closely, it may have been an on-camera shoot, but you get the idea!)
And here's your bonus Celebrity outtake...the late Mr. Jack Palance!
