In 1984's Splash, mermaid Daryl Hannah emerged from the ocean with perfectly crimped tresses.
Bond Girl Ursula Andress had a white-hot bikini—and sexy slicked-back hair to match—in Dr. No.
Penélope Cruz played Blackbeard's daughter in Pirates of the Caribbean: On Stranger Tides and has the hat-hair to prove it (though she also has some great textured waves!).
Forget Dudley Moore; Bo Derek's cornrows were the coolest thing to come out of the 1979 film, 10.
While lounging seaside in Two for the Road, Audrey Hepburn made a statement with enormous sunglasses and a pixie cut.
In The Blue Lagoon, Brooke Shields gets stranded on a desert island. The silver lining: sun-drenched ombré hair color most people would pay for.

In The Net, Sandra Bullock's classic black-bikini-and-messy-bun combo lured a handsome (yet deadly) admirer.
Annette Funicello's teased hairdo had magical staying power in 1965's Beach Blanket Bingo (we shudder to think how many cans of Aqua Net hairspray were sacrificed).

Between washing that man right out of her hair, Mitzi Gaynor fell into her South Pacific costar's arms pretty easily.
