Only have pics of all four actors, the director and John Woo 😦 … dont know if any other celebrities attended the event or not.
The theme song by Shin Hye Sung is already released (I think) because the MV is already released. Besides Shin Hye Sung, other singers that participated in this OST are Tei and Brown Eyed Soul. Shin Hye Sung is singing “Timeless Memory” (da theme song la) while the other 2 songs, “Nothing Better” and “Forgiveness” will be sung by Tei and Brown Eyed Soul (not sure who sings which song). I need to get my hands on this OST! 🙂
