The Divine Sarah's enormous popularity cannot easily be overstated. She wowed the world with her performances for decades.
She's also known for playing Hamlet—and for playing the role with remarkable energy and verve.
I don't know how this clip made its way onto YouTube, but it did. It's a nearly-two-minute-long film of the duel scene from Hamlet, and it's the only extant clip of her in that role:
The giant chicken silhouette adds an air of the surreal to the clip, but I don't think we can read much into it beyond assuming that it's part of the film developing process. Either that or it's a shadowy echo of Horatio's lines in the play's first scene:
Or is that reading too much into it?. . . . . . . . . . . . . . . . . . . . . . . . I have heard,
The cock, that is the trumpet to the morn,
Doth with his lofty and shrill-sounding throat
Awake the god of day; and, at his warning,
Whether in sea or fire, in earth or air,
The extravagant and erring spirit hies
To his confine: and of the truth herein
This present object made probation. (I.i.149-56)
