If there's been one knock against Isaiah Mustafa's second Old Spice ad, it's that the spot appears to use CGI—something the original famously did not. But actually, Mustafa says this one was completely CGI-free, too. In the interview below, from G4's Attack of the Show, Mustafa walks you through the new Wieden + Kennedy ad step by step. Apparently, his legs in the opening shot are prosthetics, and he was wearing a harness and wire the entire time, which is how he's able to swan dive into the hot tub. The one secret he won't divulge is how he changes from shorts into jeans at the end—though he says that was the hardest part of the sequence, which took "36 or 37 takes" to get right. The whole thing was shot on a custom set built—including the man-made waterfall—on a lake in Vallermo, Calif. One final piece of trivia from the G4 clip: Smelling Mustafa in person can lead to pregnancy in women. Via Consumerist.
