While many other Hollywood Dads qualified for the title, my pick goes to Orlando Bloom.
I first saw him on The Lord of The Rings as the Elf, Legolas. Who knows behind the silvery long sleek hair is this curly brown haired guy. Since then, he had gone to play Will Turner and marry (and divorce) Supermodel Miranda Kerr. He has one son, Flynn... who seems to adore swashbuckling as much as his dad.
