Joshy is known as the hit maker of Malayalam films. Joshi's role in making Mammootty a superstar is not small. New Delhi, directed by Joshy is one of the super hit film in Mammootty’s career. The actor-director duo has given several blockbuster films in the past like Sangham, Nair Saab, Mahayanam, Kauravar, Dhruvam etc. January Oru Orma, No 20 Madras Mail, Naduvazhikal and Naran were some of the hits of Mohanlal presented by Joshy.

Superstars and megastars are the same for Joshy in shooting locations. At times, Joshy blasts at actors in order to make the film even better. He has the history of cancelling a film titled ‘Aarathri’ after Mammootty dozed off in the sets. Shooting was restored after the mega star tendered an apology to the director.

Prithviraj too had experienced Joshy’s wrath. The incident happened during the shooting of Robinhood. There is a scene of Prithvi riding a bike. Joshy didn’t like the scene even after taking ten takes. He lost his temper, yelled at Prithi and told him ‘first you go and learn to ride a bike’. Though Prithvi got scared in the beginning, the advice of senior technicians and stars about the behaviour of the director calmed him.
