Oscar award-winning actress, Lupita Nyong'o, has revealed why her mother, Dorothy Nyong'o, was not interested in watching her new movie, Us.
During an interview at Good Morning America (GMA) show, Lupita disclosed that she tried to get her mother to watch the new movie in vain.
The international movie star stated that the film was terrifying and her mother opted to close her eyes and cover her ears.
"My mom was terrified of seeing this film," Nyong'o told GMA." "In fact, she watched it with her eyes closed and [covered] her ears so she hasn't really seen it."
In the movie, a family of four, the Wilsons, are confronted by monster versions of themselves.
Lupita's role is being a mother of two by the name Adelaide Wilson as well as a scarier version of the same character called Red.
She revealed that playing both roles took a very heavy toll on her emotionally.
During a separate interview with BBC, Lupita told journalists that to make Red sound distinctive, she had to mimic a voice condition called spasmodic dysphonia.
"It's a condition that's brought about by trauma, sometimes emotional, sometimes physical and sometimes inexplicable.
"It's where your vocal cords start to spasm and they create this irregular abrupt pattern of air," she explained.
For the film, Lupita met people with the condition and worked with a voice therapist to make sure she didn't damage her vocal cords.
The renowned filmmaker also went to great heights to stay in character.
"I went a little more method than I usually do where I stayed in the vocal posture for the whole day and I would remain isolated in a room festering," she stated.
