Our blog buddies over at Engadget put us onto this funny little tidbit. Apparently annoyed at some fans who doubted his identity (as "Walter B") while trolling a discussion forum on his forthcoming movie, Mr. Die Hard put up rather than shut up. Challenged to prove his identity Bruce Willis offered to video iChat one of the biggest doubters, who duly posted the evidence for everyone to see. Well it's good to see that when he's not saving the planet from terrorists, asteroids, or other baddies, Willis is willing to defend his artistic integrity in online forums with his Mac.
