It's years since Annette Kellerman became the first person to appear nude in a Hollywood film. But this was just one of many remarkable events in her life. She sat naked on a tree branch, her arms stretched upwards, but her hair largely covered her breasts.

Annette Kellerman is regarded as the first star - male or female - to appear nude in a mainstream Hollywood production.
