Onaayum Aattukkuttiyum (English: The Wolf and The Lamb) is a 2013 Indian Tamil-language neo-noir thriller film written, directed, and produced by Mysskin.

[1] Sri of Vazhakku Enn 18/9 fame, Mysskin, and Shaji Chen play the lead roles in the film.

A man with a gunshot wound collapses on the side of a road, where passersby notice him but avoid taking any action.

All of them are actually there to light candles in a memorial for the blind man and woman’s son, who was inadvertently killed by Wolf while working for Thamba.

The actor-director is in sparkling form as he returns with a career-best in this dark, gritty, moody, philosophical metaphor-infested chase film that’s mostly brilliant.

Onaayum Aattukkuttiyum compares well with world cinema but with a little more restraint and understatement, Mysskin has every potential to breakout at the international festival circuit and make us proud someday".

[13] Sify wrote "Onayum Aatukuttiyum is a gripping edge of the seat emotional dark thriller which also entertains.

[14] Haricharan Pudipeddi of IANS gave 4 stars out of 5 and wrote "OA arrives sans fanfare, but it sweeps you off your feet with an engrossing narrative, told mostly through one night.

[15] The Times of India gave 3.5 stars out of 5 and wrote "on the whole, Onaiyum Aatukuttiyum, while a rung below Anjathey in the filmography of Mysskin, is a tense thriller, one of the interesting films of the year, that is yet another showcase for its maker".

[16] Rediff too gave 3.5 stars out of 5 and wrote, "Mysskin has scripted a brilliant tale filled with human emotions and dark humour, cleverly maintaining the suspense element in the film until the very end".

[17] The New Indian Express wrote, "Mysskin’s wolf and the lamb saga is refreshing, exciting and offers a different viewing experience to Tamil audience".

[18] Behindwoods gave 3.5 out of 5 and wrote "Mysskin’s Onaayum Aattukuttiyum is marked by apt performances, engaging screen play, intelligent narration and a sincere execution accompanied by technical flashes of brilliance.

[20] Sudish Kamath later picked it as one of five films that have redefined Tamil cinema, writing, "Mysskin hits peak form as a storyteller with the most evolved sense of visual grammar in this part of the world".

Even though it performed fairly well at the box-office it didn't get the recognition at first, it has been called one of the best Tamil films of all time in several lists.
