Aaram Thamburan (The Sixth Lord) is one of the most successful Malayalam films and was directed by Shaji Kailas starring Mohanlal as Jagannadhan alias Jagan. This is probably the first in a series of films in which Mohanlal played larger-than-life roles, the others being Narasimham and Ravanaprabhu and Thandavam. This film's songs are immortalised by the compositions by the legendary Malayalam music director Raveendran. The song Hari Muraliravam goes down in Malayalam Film Songs History as a masterpiece delivered by the rich voice of another legend, Yesudas.

The acting of Mohanlal and Manju Warrier have been worth mentioning. Manju has given a spectacular and natural performance and can be easily termed as one of her superlative performances.

Jagannadhan (Mohanlal) alias Jagan makes a friend of him (Saikumar) to buy an old kovilakam for him as a return of favour. Jagan starts to live in the tharavadu and slowly gets involved in the life of people around him. People see him as the 6th Thamburan in the regime, which everybody thinks lost its roots. He clashes with the Kolappulli Appan Thamburam (Narendra Prasad) who prevents a religious possession.

It is revealed later than Jagan actually is the son of the priest who was killed in the feud between the two families. Jagan outwits and outcomes the Appan Thamburan and his allies and conducts the possession. Though he tends to leave the place with his love Unnimaya (Manju Warrier) after that, he obliges to the people's wish and stays back.
