Shark Freediving

Probably many of you never heard of Esther Williams, but it appears that in her peak days she was a pretty well known actress in Hollywood. As a former swim athlete she made several underwater musicals where she swam in her typical mermaid style way, shot and edited in such a way as if she could breath underwater. It gives a pretty and also somewhat funny picture as you can see in the video below.

She had a few oxygen related accidents and even some hearing problems because she broke her ear drums several times during shoots for her films. More about her on her own website or her wikipedia page.

I wonder how long she really could hold her breath with all the shooting and training she did for her films.
