Udayon is another block buster from Bhadran with Mohanlal in a dual role.

The story revolves around 74 year old Soornad Kunju ( Mohanlal), a settler who built an empire on his own by years of toil on hilly forest land. A self made man, he is obstinate and even broke laws in his quest to built up his empire. 

He had five children, in two marriages including Rarichan (Innocent), Pappoyi (Mohanlal), Itti (Babu) Molly (Sukanya) and an eight year old son from a second marriage. Kunju wants his sons to be like him, toil on land and make money. He even gives each of them some acres of land but none of them was interested in farming. Rarichan wanted to be a clock mechanic, Itti was interested in politics while Pappoyi who was tough like his father did not have, or agree with his father's obsession of achieving things by any means. He spend his time gambling and doing nothing worthwhile.

Kunju has no respect for his children and never understands their problems. He is not ready to part with his money even to get his daughter married. 

Ichamma (Bindu Panikkar) is Kunju's only sister and she has three sons, Mathan (Kalabhavan Mani), Thoma (Jagathy) and Pothan (Manoj K.Jayan). They find that Kunju has cheated Ichamma of five acres of land. When Ichamma demands her land back, Kunju reuses to give it back to her. This causes a rift in the family and Ichamma's children is out to get him. The rest of the story deals with the conflict in the family between Kunju, Ichamma and their children.

Udayon has heavy dialogues and action. Music by Ouseppachan are good but some times seem out of place in context. Cinematography by Ramachandra Babu is good.

Mohanlal as rough and tough Soornad Kunju, with negative shades gives a wonderful performance. He carries the film on his shoulders. As the son, the role is nothing new, he has been doing the same role for the umpteenth time. Manoj K Jayan is good in his role. The rest of the cast is okay.

Overall it is a must see film for Mohanlal fans.
