K-pop act Super Junior’s Choi Si-won left an encouraging comment on his Instagram account Monday for Avengers actress Claudia Kim.

Standing behind a trolley stacked with suitcases at Incheon airport, Choi captioned his photo with the message: “Heading to Hong Kong now. Claudia! Good luck with the interview today. I hope the new Avengers breaks the box office record!”

A singer-turned-actor himself, Choi recently participated in the 2015 Chinese film, “Dragon Blade,” alongside Jackie Chan.

The 28 year-old star is currently in Hong Kong for the Tuesday screening of his upcoming thriller film “Helios” at the Charity Gala Film Premiere, an event designed to raise awareness and funding for young entrepreneurs in the region.
