The actor also revealed the difficulties of filming, especially being in such an aggressive atmosphere at all times.�He said, "There were times that I was exhausted on the set even though I wasn't doing anything. Psychologically, I wasn't in the best of mood and there were times that the mood of the scene would translate to the mood of the set. Towards the middle and end, I felt psychologically drained."�
