Veteran actor Dimple Kapadia's nephew and producer-entrepreneur Twinkle Khanna's cousin Karan Kapadia is set to make his Bollywood debut with Tony D'Souza and Vishal Rana's upcoming yet-untitled film.

"I've learnt to ride a horse and the bike. I've been swimming and I trained in martial arts for six months in Bangkok," says Karan, whose debut film will be directed by Behzad Khambata.

The actor learnt the craft from Jeff Goldberg Studio. He says he was earlier obese at 112 kg, but following regular gymming, is now a fit and healthy 88 kg on the weighing scale.

Karan's brother-in-law and actor Akshay Kumar shares a close association with D'Souza. They have worked together on two films -- Blue and Boss.

Jointly produced by Shrikant Bhasi, Nishant Pitti, D'Souza and Rana, the film is slated to release next year.
