Filmmaker Imtiaz Ali, who is working with superstar Shah Rukh Khan in his forthcoming directorial, says he is impressed that the actor hasn't forgotten his roots in theatre.

Imtiaz, who too has an affiliation towards theatre, spoke at the Colors Khidkiyaan Theatre Festival 2017 here on Wednesday evening.

Talking about working with Shah Rukh in the film - tentatively titled 'The Ring' - Imtiaz said: "We talk a lot about Delhi theatre. I didn't know that he would be still in the habit of performing in the way that he used to when he did theatre. His approach is very theatrical."

"Every day he talks about his theatre experience in Delhi and I am very glad about that."

Talking about the festival, Imtiaz Ali said that since he himself comes from a theatre background and is now into films, it's a "unique initiative" which "blends theatre and film industry together".

"I'm really happy that there is a festival which is a confluence of theatre and films. I'd like to encourage all the people who are aspiring actors or filmmakers to indulge themselves in theatre as it gives certain attributes and certain strengths that will always be beneficial in both theatre and films and in life in general," he added.

The first day of the festival which began on Wednesday, also featured a tribute to the late veteran actor Om Puri and a musical performance by Piyush Mishra.

Colors Khidkiyaan Theatre Festival 2017 had two theatre presentations of Smita Bharti's play "Jug Jug Jiyo", featuring Dolly Ahluwalia, Ankita Bhargava, Meghna Malik and Amit Dolawat.

Hindi film fraternity members like Naseeruddin Shah, Vikas Bahl, Nitesh Tiwari, Dia Mirza, Prachee Shah Pandya, Karuna Pandey, Suchitra Pillai and Dheeraj Dhoopar also came to support the festival.

The five-day long festival will also have a mix of superlative theatre productions and workshops, panel discussions moderated by Anupama Chopra and Arunabh Kumar, a masterclass by casting director and acting coach Mukesh Chhabra, script-reading sessions and a short film corner.
