[3] He worked in more than 100 Malayalam movies with the areas of his contribution including script, story and dialogue.

Appachan read Dennis' novel 'Aakashathinu Keezhe' published in Chitrakaumudi weekly and expressed his interest to make a movie based on that novel.

However, at the last minute, some problems arose regarding the location, and Appachan asked Dennis to find another story.

Mammootty, who acted as a hero in 24 of his films, had not been on speaking terms with Dennis for over 12 years.

The beginning of MACTA – Malayalam Cine Technicians Association was in fact formed as a backdrop of this rift with Suresh Gopi.

The issue with Suresh Gopi which eventually led to the formation of MACTA started on the location of a movie named City Police scripted by him.

Along with John Paul, Dennis went to the shooting location of Joshiy's film Bhupathi.

After that, Suresh Gopi had acted in four to five films of Kaloor Dennis including Marc Antony and Paranju Theeratha Visheshangal
