Nithya Menen was cast for the female lead despite a ban imposed upon the actress by the producers's association. Footballer Suvith Krishna, who represented the Kerala team from 2004 to 2010 and is a professional model, made his film debut as a keyboardist in the song sequence \"Appangalembadum\". Singer Reju Joseph's son Jagan Reju played the role of teenage Kareem. Anwar Rasheed says that he accidentally saw Jagan's Facebook profile and was stunned by the boy's resemblance to Thilakan in his teenage years. Jagan says, \"Anwar Rasheed Sir just saw my photos on Facebook. It was an unexpected call and when I went to meet him, he was surprised and asked me whether I will play the teenage role of Thilakan Sir.\" The only drawback was that Jagan was too tall compared to Thilakan; he covered this by taking some close and mid-close shots. Jagan was shown only in flashback without any dialogue.
\"Appangalembadum\" sung by Anna Katharina Valayil is based on a traditional Mappilappattu, which is sung during Muslim weddings. The song is portrayed in the film as being performed by a fictional band named \"Kalumekkaya\" (meaning Mussels) which is known for combining traditional folk songs with western music. The song became popular among children and young adults and was one of the biggest hits of the year.
The film was scheduled to release on 11 May 2012 but, due to some issues, the release was delayed. In July 2012 some media reported that the release would be delayed again as it was not approved by the Animal Welfare Board of India (AWBI), which received a complaint stating that camels were used in a song sequence without permission. The reports said that the releasing board prevented the film's screening. Director Anwar Rasheed denied the charges and said, \"The song sequence was shot in Rajasthan after getting the permit and there is no complaints against the movie.\" 1e1e36bf2d
