There are three phases to any role that’s played in a bollywood movie; the rules are made especially stringent if it’s an Akshay Kumar starrer. Here are a few samples.
a. The mother
#1 The caring mother (until her Police officer husband is shot by the villains)
#2 The hardworking widow (after his death)
#3 Photo on the wall.
b. The beautiful sister
#1 The playful chirpy girl.
#2 Falls in love with a bad guy.
#3 Raped and killed (usually the lengthiest scene in the movie).
c. The Heroine
#1 A Social worker/college student.
#2 Falls in love with the hero (charachterised by songs at unwanted times).
#3 Marries the hero (in case of availability of another heroine, refer b.#3)
...and the formula continues to create sensational hits.
