Blessy is a Malayalam film director and screenwriter who was earlier associated with veterans of film industry such as Padmarajan and Lohithadas and was an assistant director to both of them. Blessy got his first break as a director and screenwriter in the movie ‘Kaazcha’ in 2004. It was his debut movie which depicted Mammootty as a film operator who tours the countryside with his 16 mm projector and shows his films at festivals and functions. The film also dealt with an orphaned boy who was a victim of Gujarat earthquake and meeting Mammootty changes his life. This film fetched him Kerala State Film Awards. The biggest asset of Kaazcha is the story, and screenplay by Blessy and even Mammootty proved that no other actor can match up to his skills of acting in such roles. He was the heart of the movie.
Next year, Blessy came up with another interesting project with Mohanlal. The film was ‘Thanmathra’ (2005) which fetched him the National Award for the Best Feature film. The film had bagged five more awards from Kerala State in various categories. The film ‘Thanmathra’ portrayed the effects of Alzheimer's disease on the life of an individual and his family; the soul of the film was Mohanlal, child actor Arjun Lal, and Nedumudi Venu. The flick was a roaring success at the box office. For his third venture, Blessy repeated Mammootty once again in his film ‘Palunku’ (2006) and again created the same magic; it fetched Mammootty Kerala State Best Actor award once more. The film was noted for its relevant plot, the performances of the lead actors, and the directional excellence of Blessy. The film managed to be an average grosser in the box office.
The next project of Blessy was ‘Calcutta News’ which was shot in Kolkata. The film had Dileep, Meera Jasmine and Indrajith playing the lead role. The film depicted how an innocent girl from Kerala ( played by Meera Jasmine) was saved from falling into the trap of trafficking. The film gave ample opportunity to actor Dileep to play a different character. It was a marginal hit movie in Kerala. In 2009, he had cast Mohanlal again for his successful project ‘Bhramaram’ (2009), and the film was widely appreciated for Mohanlal's performance. In 2011, he wrote the screenplay and directed the film Pranayam, which had Mohanlal,
in lead roles. The film received positive reviews and also a commercial success. It was Mohanlal's 300th film, and it was the third time Blessy and Mohanlal signed a bond together. It got Blessy the Best Director Award at Kerala State Film Awards. Also, the movie received multiple awards in Kerala from various TV channels and Film Critics’ Awards jury.
In 2013, Blessy made another film ‘Kalimannu’ which has Suhasini Maniratnam in a supporting role. The film was not in the league of Blessy's other classics but a watchable movie indeed. In 2015, Blessy is making ‘Aadujeevitham’ where Prithviraj will essay the lead role. The film is based on a novel that has won National Sahitya Academy Award.
