Rai started his career with "Strangers" and "Thodi Life Thoda Magic" but both the films were unable to impress the audience.
It was the success of his 2011 Kangana Ranaut-starrer "Tanu Weds Manu" that helped Rai establish a foothold in the industry. He then went to direct two superhit films "Raanjhanaa" and "Tanu Weds Manu Returns".
He even attained success as a producer with "Nil Battey Sannata" and "Happy Bhaag Jayegi" and is currently backing "Shubh Mangal Savdhan", featuring Ayushmann Khurrana and Bhumi Pednekar.
Apart from "Shubh Mangal Saavdhan", Rai also has other interesting slate of films in his kitty, such as, Rajkummar Rao-starrer "Newton", "Happy Bhaag Jayegi" sequel and Anurag Kashyap's directorial "Mukkabaaz", about a boxer from Uttar Pradesh who falls in love with a Brahmin girl.

"There's also a constant endeavour to associate with content which resonates with the above sentiment, and you'll see that in films like 'Newton' and 'Mukkabaaz'. I believe stories come from experiences, either your own or of the ones you can relate to.
The 46-year-old director-producer believes cinema is a reflection of society - which is ever changing and growing.
"As a filmmaker, I consider it my privilege to have a medium of expression that can reach so many people with my thoughts and if presented well, I know that people will embrace it too."
Talking about the film, Rai says, "It's an out and out entertainer. I have always been excited about films that blend in unique concepts and characters against the backdrop of a mundane Indian household. It helps bring out the characters' nuances and make them stand out, which we don't usually notice in daily life.
"I'm introducing new characters with this film. The woman of today is not the same as four years ago and we should pay attention and respect that. The female protagonist, Sugandha (Bhumi) is as distinct as Tanu and Datto were from each other in 'Tanu Weds Manu Returns'," he says.
"Ayushmann is a brilliant actor, who can confidently shine in the simplest of characters and retain the simplicity which is a great quality for an actor. That's why he becomes an obvious choice for a lot of roles.
"And I will say the same about Bhumi, an actor selflessly available to a story. It was great working with them," he says.
Rai is currently working on one of his highly-anticipated films - his next directorial project with Shah Rukh Khan.
