However, there is no official confirmation yet from Kapadia, 61, regarding the same.
"Tenet" will not be Kapadia's first appearance in an English language film. She was noted for her portrayal of the title role in the American production "Leela" (2002).
As per reports, "Tenet" is Nolan's follow-up to his Oscar-nominated war drama "Dunkirk" that earned the noted filmmaker his first best director Oscar nomination.
"Tenet", an action epic film, will be filmed across seven countries.
Kapadia was launched by renowned filmmaker Raj Kapoor at the age of 16 in teen romance "Bobby" (1973). She received acclaim for her performances in films such as "Rudaali" (which earned her a National Film Award for Best Actress), "Gardish", "Krantiveer", "Dil Chahta Hai", "Being Cyrus", "Finding Fanny" and others.
The actor, who married superstar Rajesh Khanna, was last seen in Anees Bazmee's 2015 film "Welcome Back".
