This is Noma Dumezweni who plays the lead female role in a 2016 British theatrical production, along with actors Jamie Parker, Paul Thornley, and Poppy Miller. The play is written by Jack Thorne, based on a story co-written by the play's director John Tiffany.
Dumezweni's selection, given her race and Swaziland origins, caused much comment with the other co-writer of the original story pointing out that the character's race had never been specified as white.
