Johnny Depp was back on set today to resume filming on "Pirates of the Caribbean: On Stanger Tides" in London -- where we got a closer look what it takes to get him to look like Captain Jack Sparrow.
Depp arrived on set with his hair down, wearing jeans, a t-shirt and a plaid shirt -- but then re-emerged with his hair in braids ... which were then covered up with a wig.
