EXO's D.O. was asked to introduce the movie to viewers, and adorably stumbled over his words to which his noona co-stars helped out. When asked which co-star did he want to work with the most, D.O. chose veteran actress Kim Young Ae, commenting, "I was really looking forward to working with her. But I didn't have any scenes with her."

When asked which co-star was different from his or her expectations, D.O. chose Yeom Jung Ah who plays his mother in the movie. He explained, "I thought Yeom Jung Ah was going to have a scary first impression. But when I met her for the first time to film together, [I found out that] she is really friendly, and she felt like a real mother to me from the start."

D.O. greeted the viewers, sharing, "The movie 'Cart' will premiere in November. It's a warm movie that is perfect for fall so please look forward to it, and I hope that you give it a lot of love. Thank you!"
