After the success of Makkal Aatchi, the actor Mammootty and director Selvamani reunited for another political film titled Arasiyal. The director, prior to release, played down any potential controversial story plots and indicated it would be more about a politician's personal life rather than his work. The team shot across North India in 1997 with scenes also filmed at the Golden Temple, Punjab.^[1] The film's shoot was delayed for few months due to poor health of Mammootty and Jai Ganesh and the 1997 FEFSI strike.^[2]

The music was composed by Vidyasagar.^[3] The film marked the debut of singer Harish Raghavendra in cinema.^[4][5]

The film was initially supposed to release in the Diwali season of 1997,^[2] but got postponed to 12 December.^[6] Ji of Kalki praised the performances of Mammootty and Mansoor Ali Khan, Liyakath Ali Khan's dialogues and Panneer Selvam's cinematography but felt since many of the political incidents have been analysed earlier, it feels like watching action replay with no thrills.^[7] Despite the film receiving primarily mixed reviews, Mammootty's performance was well noted by critics and fans.^[8] The film won the Tamil Nadu State Film Award for Third Best Film.^[9]
