Illusion becomes reality) is a 1978 Indian Tamil-language film, directed by K. Balachander,[1] starring Kamal Haasan, Sarath Babu, Sumithra and Hanumanthu, and introduced Shoba to Tamil cinema.

Though Indumathi too starts liking him, she is too egotistical to show her romantic side to Sanjeevi as she doesn't want to remove her stubborn attitude "mask".

Mouli said that he was given the liberty by Balachander to insert comedy sequences wherever he wanted and that he wrote 16 scenes for the film.

[7] For the role of Kasi, Balachander chose stage actor Hanumanthu after he was impressed with his performance in the play Sampoorna Ramayanam.

[8] Balachander stated that he had an egotistical girl (Sumitra) fall for the macho antics of the hero (Kamal Hassan) "to lend credence and strength to the plot" and felt she was in juxtaposition to the innocent victim character played by Shoba.
