"I have worked in Tamil, Telugu and Kannada films. I have done as many as 35 films here. Though the industry is always one, whether it is from the days when Jeetendra used to do southern films and directors used to come here and make Bollywood films," said Sonu.
He feels earlier actors were confined to films in their language, and that has changed over time.
"It was just the language barrier that kept people away from doing Telugu films or Hindi films, but now everything is coming on one platform and people are ready to explore," he added.
