People had just a vague idea of who McInnis was before 'DOTS'; however, thanks to the series' explosive popularity within and outside Korea, he is now recognized far more by the public. 

The actor mused during an interview with '@star1,' "I had no idea that 'Descendants of the Sun' would be so successful. I think I've done around 7 each of dramas and films, and ['DOTS'] was the biggest hit of them all. Now, many people recognize me when I'm out and about, asking me for autographs, and I'm happy that I've gained a bigger following of fans."

McInnis also detailed his first impression of Song Hye Kyo during the interview, saying, "A part of the eleventh episode shows Argus holding Kang Mo Yeon hostage and trying to make a deal with Yoo Shi Jin. There is a scene [during this part] where I had to tie Song Hye Kyo to a chair and threaten [Song Joong Ki's character] by striking her face with a pistol. It was so difficult for me to act out that scene. My heart was so torn. I think I was more careful because I had to act out hitting Song Hye Kyo in the face with a pistol in hand. Plus I had to pretend to cock the gun to her forehead. I was worried about her." 

However, what McInnis didn't know at the time was that Song Hye Kyo is tougher than she looks. The actor continued, "But [through that scene] I realized just how professional Song Hye Kyo is as an actress. During our rehearsal, she told me, 'I'm fine so put the gun to my head properly,' and, 'Please make the scenes where you hit me look more realistic.' Because she's such a popular actress, I was more cautious but she wasn't hesitant at all in order for good acting results. Thanks to her, I was able to act comfortably and be as rough as I could during that scene. I was thankful and I learned much [from her]."
