Kenyan Lupita Nyong’o has said the  Horror film Us took an emotional toll on her and it was exhausting as she had to play different versions of the same character

“This movie stretched me, it bent me, it cost me a whole lot,” she told the BBC’s Radio 1Xtra. Us is a horror film written and directed by Oscar-winner Jordan Peele – the man behind Get Out.

In the movie a family of four – the Wilsons – are confronted by monster versions of themselves. Lupita plays mum-of-two Adelaide Wilson and a scarier version of the character called Red.

To make Red sound distinctive, Lupita says she mimicked a voice condition called spasmodic dysphonia

“It’s a condition that’s brought about by trauma, sometimes emotional, sometimes physical and sometimes inexplicable,” she said.

“It’s where your vocal cords start to spasm and they create this irregular abrupt pattern of air.

“So I had experienced someone speaking with that condition and I got curious about it.”
