i am from india , and can tell about bollywood movies . in bollywood there is a director called mahesh bhatt , who specialises in movies containing people with mental issues .
he was into a relationship with a famous bollywood star called parveen babi , and parveen was diagnosed with schizophrenia while he was in this relationship with her . her subsequent mental breakdown affected mahesh greatly , as he himself had mental health issues because his mother was mistress of his father and his father and father's wife used to treat mahesh's mother and mahesh not too well in his childhood .
later he made a movie called 'arth' ( meaning ) in which one of the two leading actresses ( played by smita patil ) has mental issues . the hero is into this extra marital relationship with her , neglecting his wife ( played by shabana azmi ) . the character of smita was based on parveen babi .
later again mahesh bhatt regurgitated the parveen babi story in a film aptly titled ' phir teri kahani yaad ayi ' ( i just remembered your story again ) . the leading actress was played by his daughter pooja bhatt and she was shown to be a schizophrenic who ultimately dies in the movie .
mahesh dealt with his own mental issues arising from his iilegitimate birth in the film 'janam' ( birth ) starring kumar gaurav . mahesh once gave an interview saying ' before others say it , i am shouting myself ( presumably from the rooftops

) " i am a bastard ,i am a bastard !! "
