However, what McInnis didn't know at the time was that Song Hye Kyo is tougher than she looks.
The actor continued, "But 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.
