1: Nenokkadine (English: 1: I am alone) is a 2014 Indian Telugu-language psychological thriller film written and directed by Sukumar. Produced by Ram Achanta, Gopichand Achanta, and Anil Sunkara as 14 Reels Entertainment and distributed by Eros International, the film features Mahesh Babu and Kriti Sanon in the lead roles (Sanon's Telugu cinema debut). Nassar, Pradeep Rawat, Kelly Dorji, and Anu Hasan appear in supporting roles. Mahesh's son, Gautham Krishna, made his debut in the film as a younger version of the protagonist.

1: Nenokkadine revolves around the search by Gautham (a schizophrenic Indian rock musician missing 25 percent of his brain's grey matter) for his parents, whom he believes were murdered by three men. Sameera, a journalist, convinces him that he is an orphan and is hallucinating. When Gautham kills one of the "imaginary" men for his psychological satisfaction, he realises that the dead man is real and leaves for London to find his roots and the other two men behind his parents' death.

Sukumar began working on 1: Nenokkadine's script after completing 100% Love (2011), making a bus driver's tale about a boy who claimed that his parents were murdered on his bus the film's base. R. Rathnavelu was the film's director of photography, and Karthika Srinivas its editor. Devi Sri Prasad composed the soundtrack and background score. 1: Nenokkadine was introduced on 12 February 2012 and principal photography, which began on 23 April 2012, was completed in late December 2013. It was filmed in London, Belfast, Bangkok and Indian cities including Hyderabad, Mumbai, Goa, Chennai and Bangalore.
