Mermaid in trouble

Astrid Bergès-Frisbey stars in Pirates of the Caribbean: On Stranger Tides (number four in the series) as a mermaid who's taken captive by evil pirates.

Her bondage is actually quite ingenious; she's left tied with her wrists above her head while seated in a shallow pond.

With her legs submerged in water, they revert to a fish tail. Her bound wrists keep her in the pool, which stops her from climbing out.

A suitor tries to rescue her, but she's quickly re-tied.

She's eventually rescued.

And before you think I'm getting all fishy on you, there is a barefoot bondage scene in this movie. It comes at the very end, with Jack Sparrow rowing Penélope Cruz's character, who sits with her hands tied behind her.

Unfortunately it's a very brief scene, lasting just seconds.

And, these shots are actually of Cruz's sister, who stepped in to play these scenes because Penélope Cruz was pregnant when she shot this movie.
