While promoting the movie on TV show - 'Yaar Mera Superstar' the 58-year-old actor confessed that he wrote 'Ghayal Once Again' as he wanted to relive the genre of the movies that he worked in the past.
"When I started working, films like 'Betaab' (romantic) and 'Arjun' (action-drama) released and they brought in a different genre in Bollywood. And that is the kind of movies I believed in," he said in a statement.
"In the past few years, I felt direction-less and then I thought I should go back to my genre of movies which I believed in. So I wrote 'Ghayal Once Again' to go back to my roots," he added.
Sunny, son of legendary Bollywood actor Dharmendra, is known for playing roles of an angry young man on-screen.
The 'Gadar' star has donned hat of a director and writer for his upcoming film 'Ghayal Once Again'.
The movie is a sequel of his 1990 blockbuster hit 'Ghayal' starring Meenakshi Sheshadhari.
