The ghoulish scalawags of the Caribbean have set sail and are expected to make landfall at a theater near you on May 20th of this year. The fourth installment of the Pirates of the Caribbean franchise, dubbed On Stranger Tides, appears to be bringing with it plenty of swashbuckling action, many new characters, and hopefully a reignited plot that will right this waterlogged franchise and get it back under full steam. Rob Marshall is directing this time around.

In the meantime, Disney has released a series of concept sketches that give us our first looks at the zombie pirates Jack Sparrow (Johnny Depp) will encounter on his race to the fountain of youth before his arch-nemesis, Captain Barbossa (Geoffrey Rush) gets there first.

Check out the character sketches below:
