not if ther is political backing for the film
the films about the soldiers that recieved the Vir Chakra i think amongst hem were 3/4 singhs. one was balwan singh who was 'the toughest officer of them all'.
about a film on 1984 well theres hawayein, but it wont go into more detail than that bcos of govt cencorship, but if an interational organisation was approached and they made 1 then u may get a more realistic view of events.
