Final answer:
There is no mention of Aunt Madina or a movie star she was compared to in the provided text. More context about Aunt Madina is needed to accurately respond.
Step-by-step explanation:
The text provided does not mention Aunt Madina or a movie star to which she was compared. Instead, the provided references from different stories concern orientalism in films, a parody performance by Auntie Aissatou, and the unique approach of casting in a musical production featuring the character Aunt Eller.
Unfortunately, based on the information given, there is no way to determine which movie star Aunt Madina might have been compared to in an unspecified story.
To provide an accurate response, more context or an extract specifically related to Aunt Madina and the said comparison would be required. Without this, it's impossible to draw a connection between Aunt Madina and a particular movie star.
