"It is better if he is an actor because he knows what actors go through. I've always liked directors who are actors as well. It's always an advantage. The disadvantage is when directors have not been actors but are wannabe actors. That is difficult. They haven't done acting but they have an actor within," Randeep said.
"Today anybody can do anything. They can sing too, with help of self-tuning," Randeep added.
Randeep will be next seen in Do Lafzon Ki Kahani, helmed by actor-director Deepak Tijori. In the romantic-drama, the 39-year-old actor had to beef up for the role of a Mixed Martial Arts fighter and says the process was extremely grueling.
"Transformation for this film was more difficult. Two hours in the morning (I used to practice) mixed martial arts, two hours in the evening body building. I used to take pain killers," the actor said.
Randeep, shot the movie before filming his recent Sarbjit where he had to lose a lot of weight, which the actor says, he wouldn't advice anyone to do.
"My sister helped me a lot. I wouldn't want anyone to try this at home. To lose and gain 30-kg of muscle mass in a year is not healthy at all. I am still not fully healthy today," he said.
"I wouldn't advice anyone to try this...To lose that for 'Sarbjit' was heartbreaking. Every day when I was losing this muscle I used to look at myself in the mirror...It was very hard," he added.
The film, which also stars Kajal Aggarwal, is scheduled to release on June 10.
