Seeing the last 6 contestants till now, following impression I have in mind in terms of roles that are suitable ... or similarity with Big names.
PS - i understand big stars are uncomparable this is just referential and strictly IMO.
Piyush - James kind of movies, serious roles.
Sabina - Fun loving extrovert kind of roles, Ash kinds.
Chandani - Karishma/Juhi kinna of roles.
Prabjhot - Common man roles like Anil Kapoorish type in the 90's
Gaurav - Lover boy kinna of roles, won't suit the action hero kinna of movies.
Rachel - Tabu kinna of roles can also flip back from modern to ethnic roles.
What impressions have they made on your minds? don't say none😆
