Well done; these guys did a nice bit of editing, I'll give 'em that much, enough that I am not 100% it's fake, but here's the evidence I think it is. I used to work for a tourist company filming at the Farallon Islands and I quickly had to learn how to blend in my footage from South Africa to match with the murky waters of the Farallones so it appeared as though these tourists enjoyed spotting great white sharks from their view in the cage (all for their souvenir DVDs) Yes, I'm saying I have faked footage and yes I'm saying that 95% of the time you DO NOT see white sharks on cage-diving trips to the Farallones so consider yourselves warned before you shell out the $900.
Anyway, heres' why I think this video is fake.
By the way, I'm releasing footage of myself "fending off a white shark" to the networks next week to prove that journalists will publish anything shark related without investigating it.
