Arrrgh, matey! The Pirates of the Caribbean star went all out with his signature bandana and dreadlocks for his role as Captain Jack Sparrow.
John Travolta
The Hairspray star had us fooled as he played the sweet and overprotective (and female) Edna Turnblad in the big-screen musical.

Now this is what you call a rock star! The Rock of Ages star travels back to the '80s for his role as Stacee Jax.

Michael Douglas' costar also has a special look of his own in the HBO special. The actor drives us wild in full chauffeur attire with his longer head of hair.

They may want to look intimidating with their guns pointed out. However, we can't get over their signature hairstyles from the classic movie Pulp Fiction.
Will Ferrell
The former Saturday Night Live castmember had us laughing nonstop with his look in Zoolander. Even his dog had a matching hairstyle worth talking about.
