Oscar winner Lupita Nyong'o has apologised for saying that she based the voice of her evil Us character on a neurological disorder.

The 36-year-old actor had come under fire after she revealed that she used the symptoms of spasmodic dysphonia as the inspiration for the strained voice of Red, her murderous doppelganger character in the Jordan Peele-directed film. During a visit to "The View", Nyong'o said her intent was not to "vilify or demonise" the disorder.
