Lin Yuan had developed a go-to crew through the few films he had directed.
The core members of this movie crew remained constant, especially the producer Shen Qing and the director Yi Chenggong.
However, when Mr. Lin announced the new movie project, although the crew stayed mostly unchanged, the director position shifted from Yi Chenggong to Du An, leaving Yi Chenggong inevitably disappointed.
Though Yi Chenggong understood deep down:
In terms of directing capability, he certainly wasn't as accomplished as Du An, the great director Mr. Lin had specifically hired from Qi Continent.
Moreover...
Du An even agreed to become a tool for Mr. Lin, in order to serve as the director of "Life of Pi". This was indeed a huge sacrifice.
Because under normal circumstances,
A director of Du An's caliber would not accept a subordinate position.
So, not only was Yi Chenggong upset, Du An was likewise aggrieved.
Shen Qing kept his position.
