EXO's D.O made an appearance at the 19th annual Busan International Film Festival not as a singer, but as an actor.

D.O made an appearance at the Busan International Film Festival (BIFF) on October 7th in support of his new film 'Cart.'

D.O recently had his first acting role in the television drama 'It's Okay, That's Love.' Now he is hitting the big screen in the movie 'Cart.' D.O plays the son of a discount store employee who helps organize a labor movement after the unfair dismissal of contract workers.

During the press conference for 'Cart' that was held on September 30th, D.O talked about his character and the difficulty he had portraying him.

"Even before I was accepted for the role, I had a lot of worries about acting as my character," he said. "He's a rebel. I wasn't like that when I was a teenager, so I had a lot of reservations about portraying him. It was difficult."

'Cart' is scheduled to premiere nationwide in the month of November.

The Busan International Film Festival is one of Asia and the world's most prominent film festivals with submissions from all over the world. BIFF kicked off on October 2nd and will run until the 11th. It is held at the BIFF Village in the seaside area Haeundae in South Korea's second-largest city, Busan.
