A recent movie titled The Man Who Knew Infinity is based on the biography of

Gives a named, dated Indian scientist (Meghnad Saha, 1893–1956) showing that prominent Indian scientists/mathematicians of the late 19th/early 20th century have well-documented lives and can be subjects of biographical works.

A student could use the pattern that 20th-century Indian mathematicians/physicists have biographies and cross-check modern-era names (late 1800s/early 1900s) as likely subjects for a contemporary film.

Mentions Bhāskara II and places him about 800 years ago, illustrating that many famous Indian mathematicians are from widely different historical periods.

A student could use the timeline contrast to eliminate very-ancient mathematicians when considering a modern film about a mathematician with a title referencing 'infinity' (which often links to modern mathematical topics).

Names Āryabhaṭa as a famous ancient Indian mathematician/astronomer, giving an example of a well-known historical figure in Indian mathematics.

A student could compile the list of named mathematicians in these snippets and then, using external basic facts (eras, known biographies), narrow which of these are likely subjects of a modern film.

Lists multiple classical Indian mathematicians (Āryabhaṭa, Varāhamihira) and notes their works became foundations for further advances—showing which names are repeatedly cited in curricula and likely recognized.

A student could take the recurring prominent names from textbooks and then check which of those have 19th–20th century biographies suitable for a cinematic biopic.

Mentions Al-Beruni as a mathematician/historian who connected India to the wider world, demonstrating that historical mathematicians from varying backgrounds are documented.

A student could use this example to remember that the subject could be either a medieval or modern figure and should verify era and biography when matching the film title to a person.
