Singer J.Arie (Lui Sum Yu) and Terence Siufay earlier sang their first duet together for the film theme song #FEAR NOT THE WALL. She said that she and Siufay originally were in the movie, but due to the film length they were both "vanished" and sang the theme song instead. "Actually earlier I sang a song with Siufay and got over a million views. However this time was an official duet. Siufay even took the highly difficult challenge and performed this film song in high octave."
