Among the group of talented individuals, Arnold Shen was with them. Seeing Lexi's stance, he raised his hand indicating them to stop and then place his erected index finger in front of his lips to silence the already silent group.
In his eyes, this was the perfect chance to proved to this colleague that the person he adamantly squeezed as Chang'e was right. After all, he received a call earlier and one investor wanted to place the actress name Che Diayu as Chang'e. However, Arnold Shen had seen the girls acting skills and even if he said that she's not bad, it just too mediocre and was certain that she wouldn't give justice to this important side character.
His refusal of the order, of course, lost him an investor but, Arnold Shen regarded this film with much more important than the rest of his previous project as this was his own script and his last masterpiece before he retires. Hence, he was willing to shell out more money if that's the cost of his noncompliance.
