Rock N' Roll is a 2007 Malayalam musical comedy film written and directed by Ranjith, starring Mohanlal, Lakshmi Rai, Mukesh, Lal, Siddique, Manoj K.Jayan, Rahman, Harisree Ashokan and Jagathy Sreekumar. The film tells the story of seven musicians in Chennai, the major centre of film production in South India. The film was released on November 9 coinciding with Deepavali.^[1][2] It received negative reviews and was considered a commercial disaster at the time of release. Over the years, the movie along with Mohanlal's performance has attained a cult status. Suraj Venjaramoodu's cameo role as a fraud musician was widely acclaimed and is often considered to be one of his early breakthroughs.^[3]

The film tells the story of Chandramouli (Mohanlal), a composer and drummer, of his return to Chennai from South Africa for a brief visit, and of the incidents happening in that short span. Gunasekharan (Siddique), a leading music composer, is busy with his composition for the latest film directed by Lal Jose. He feels that it would be better if he gets the help of his old friend Chandramouli, who is now busy with his international concerts. But Mouli, a fun loving and jovial musician, makes a surprise landing in Chennai and helps Guna in his work. Mouli falls in love with Daya Sreenivasan (Lakshmi Rai), a female playback singer, who is also an ardent fan of him. But because of the compulsion from her parents and fiancé, Vivek (Anoop Menon), she moves back to Mumbai. Mouli plots a plan with his friend Thabala Balu (Harisree Ashokan) to bring her back to Chennai. He convinces Daya that he is composing a dozen songs for a film and wants Daya to sing it. Daya comes back to Chennai but is not impressed by Mouli's tunes. When she openly expresses her unhappiness over the tune, Mouli takes it as a prestige issue and composes a song entirely dedicated to her. However, Daya is unable to attend the studio on that particular day because her engagement with Vivek was fixed on that day, whom she feels is too arrogant and sophisticated for her.Knowing the fact Mouli enters the engagement venue and takes Daya to the studio for half an hour despite the opposition from her family members. Daya, who within time is fully in love with Mouli, realizes his love for her and opens her mind to him. The film ends with Mouli relaxing at a beach with Daya, but with his old habits of carefree nature and passion for girls still not gone.

The film received mostly negative reviews. On the other hand, the music was well received. Vidyasagar's music was popular especially the song "Chandamama", which stayed in the charts for many weeks. The failure of the movie also resulted in a small spat between Mohanlal and Ranjith which continued till the due came together for the hugely successful Spirit in 2012.^[4]

The film's background score is composed by Bijibal,^[5] while the songs are composed by Vidyasagar with lyrics written by Gireesh Puthenchery. The songs were very popular.

"Rock & Roll is an out and out musical entertainer set in Chennai milieu with the background of a recording studio and the world of musicians. It's a fun-filled movie with Mohanlal leading the pack of merry men." - director Ranjith^[6]
