Nala Damayanthi is a 2003 Indian Tamil-language comedy film directed by Mouli, written and produced by Kamal Haasan.

[3] Ramji Narayanaswami Iyer, a naive and docile Tamil Brahmin cook, dreams of marrying off his sister Bhagyam to a good family, as they are orphans and it becomes his sole responsibility.

Ramji reluctantly agrees for a fake marriage with Ivan's fiancé Damayanthi, a free-spirited motorbiker of Sri Lankan Tamil Christian background, and they get married over the weekend.

Damayanthi handles this situation smartly, sends all the money received for the fake marriage in their joint account to her, and makes sure her long-time friend takes care of her.

Kamal Haasan had written the script with himself in mind to play the lead role in the late 1990s, but never got down to making it because he felt it would not have been cost-effective.

[4] Through the project, he had aimed to reprise his character of the Palakkad Brahmin cook Kameshwaran from Michael Madana Kama Rajan (1990) and place him in funny situations occurring in a foreign country.

He had briefly considered making the film in early 1999 with the title of Londonil Kameshwaran after Marudhanayagam had run into production troubles, but instead chose to prioritise his commitments for Hey Ram (2000).

[9][10] Bruno Xavier, an Australia-based Sri Lankan Tamil actor, was selected to play the antagonist's role after a successful audition.

[14] Actor Kamal Haasan sang an English folk song, titled "Stranded On The Streets", which was written by Pradeep Govind.

[17] The Hindu called the film a "decent offering", adding that "a logical storyline and a well thought out script by Kamal Hassan are definite scoring points that sustain viewers' interest till the end".

Though it has some hilarious moments, it lacks consistancy [sic] in the screenplay, which is major obstacle in the smooth flow of the story.
