Azhagana Naatkal (English: Beautiful Days) is a 2001 Tamil comedy film directed by Sundar C. The film features Karthik and Rambha in the lead roles and became the third collaboration of the pair with Sundar after the successes of Ullathai Allitha (1996) and Unakkaga Ellam Unakkaga (1999). The film also featured Mumtaj, Goundamani and Senthil in pivotal roles and featured music composed by Deva. The film released on 7 December 2001 and is a remake of the Malayalam film Minnaram and is also loosely based on Jaishankar film Penne Nee Vazhga.
Indu and Chandru (Rambha and Karthik) fall in love. Indu does the disappearing act and Chandru gets engaged to Rekha (Mumtaz). Indu re-appears after three years with a little girl, who she claims is Chandru's daughter. Chandru vehemently denies it and finding Indu's presence an embarrassment tries to ferret out the truth. After many scenes of forced comedy, we learn that the girl is the illegitimate daughter of Chandru's much-married brother, who had seduced Indu's sister. After his brother's futile attempt to play the villain, Chandru latches on to Indu fast enough with no apology to Rekha. But it is not really Chandru's fault. For Rekha had done the disappearing act from the scene early enough without any explanation either.
