AceShowbiz - Hollywood joker Johnny Depp caused a stink on the set of the latest Pirates of the Caribbean: On Stranger Tides movie, by using a fart machine to play pranks on the film crew. Penelope Cruz, who appears alongside Depp in the upcoming "Pirates of the Caribbean: On Stranger Tides", first learned of the movie hunk's playful tendencies when they filmed drug drama "Blow" together in 2001.

And she learned Depp was still up to his old tricks when she joined him onset for the fourth installment of the Disney franchise. She recalls, "When I met him 10 years ago he had a plastic one (fart machine) and now, 10 years later, he has one with a remote control... He fooled me once when we were doing 'Blow'. "

"When I was doing a very dramatic close up and he kept making that sound with the machine and I kept saying (to myself), 'Who is it, is it the sound guy?' And I remember just thinking, 'I hope they are not thinking it's me.' And Johnny was there with a straight face. And now he is doing it to (producer) Jerry Bruckheimer and Rob Marshall, the director, and to everybody!"

But the Oscar-winning actress insists working with Depp is always a pleasure. She says, "We worked together 10 years ago and we had a great experience... I couldn't wait to work with him again because he's really one of the most kind and genuine people that I have ever met. And he became a good friend. He has one of the greatest senses of humor. He's really clever, really smart, kind, generous... I love working with him."
