Son of Dharmendra, Older brother of Bobby Deol and Esha Deol. He is married and has two children. Rumoured to have had an affair with Dimple Kapadia. Sunny made his debut as a teenage romantic hero in Betaab with debutante actress Amrita Singh.

Born to filmstar Dharmendra, Sunny Deol born as Ajay Singh Deol changed gears with different roles in several movies. Action roles seemed to be his forte, but he also tried his hand at romantic roles in movies like Sohni Mahiwal and Imtihaan.

From romantic hero to the rebellious, unemployed angry young man out to get justice, the blockbuster Ghayal established Sunny as the action hero in Bollywood. He was also acclaimed for his performances in movies like Damini, Arjun and Jeet.

 With Dacait (1987) and Yateem (1989), Sunny graduated into a bare-chested, bulging biceps, action hero - our desi version of Sylvester Stallone, Arnold Scwarzenegger and Van Damme rolled in one! J P Dutta's Yateem set the ideal setting for Sunny's next release Ghayal. With Rajkumar Santoshi's debut as a director, Ghayal became one of the most critically-acclaimed successes of the '90s.

Sunny acted in a number of multi-starrers like Paap Ki Duniya, Ram Avtar, Tridev and Kshatriya. Among his noticeable performances were Narsimha (1991), Lootere (1993) and Damini (1993). Narsimha created more news for the roaring affair between Sunny and Dimple Kapadia, than for his acting talents. He won an award for his role in Damini. 

The action hero went errant with a bad attempt at dancing in Jeet (1996) with Yaara o yaara.  Border, by J P Dutta, brought out the best in Sunny. Another flop in the line was Ziddi, which helped neither his career nor his love and home life.

After over 11 years of a long-lasting affair with Dimple, cruel Cupid decided to have a shot again at Sunny. Endowed with such strong capable shoulders, Sunny couldn’t help but lend it to the beautiful and vulnerable Raveena Tandon, who was suffering from a nervous breakdown. On the sets of Ziddi they became "good friends", immediately threatening the position of an already-dethroned wife, Pooja Deol, and the past reigning girlfriend Dimple. This acted as a catalyst in the husband-wife relationship, as Pooja decided that enough was enough. She tagged her husband along on almost every shoot till Sunny saw her way. And the industry is agog with the news of their patch-up. Well, that was then.

In Gadar, Sunny proved that not only that he can do action at his best, he can also excell completely in emotions. The audience liked his performances to this extent that Gadar-Ek Prem Katha turned out be the biggest hit of the year 2001.

Sunny also bagged an award for the Outstanding Performance for Gadar in the Lux Zee Cine Awards 2002. He believes he has rendered great service to the cause of promoting nationalism by making movies which revolve around patriotic themes. "It's high time we realized that we are Indians first and Gujjus or Punjabis or whatever later…

" He lives up to his real name, Ajay Singh Deol. Ajay means invincible and there's no denying Sunny's invincibility at the box-office. (even though, of late, some of the magic seems to have worn off!) A Sunny Deol starrer is sure to lure the Ludhiana crowd, or so the industry adage goes.

High on success, Sunny started scouring story ideas for his home production. When plans of making a love story based in London, called 'London', fell through, the Deol announced 'Dillagi', his first directorial venture co-starring brother Bobby. Suddenly, all his other projects were put on the back burner, even as Sunny put his heart and soul into his home production. Though the film failed at the box-office, not even the critics doubted Sunny's directorial ability.

Recently he was seen in the movie Apne is a Bollywood film directed by Anil Sharma. For the first time real life father and sons Dharmendra, Sunny Deol and Bobby Deol all star together. Shilpa Shetty and Katrina Kaif are the female leads. Filming took place in various locations including Chandigarh, Rajkot, Bangkok and Australia, and Toronto, Canada. The film has opened to a good response across India. The film has emerged as a hit at the box office in both India and overseas.
