While Michael was busy with the camera and lighting Jin was filled with stress and anxiety.
He had never acted before and the thoughts of messing things up constantly prodded him.
The fifteen-minute time period allotted by Michael also did not provide any comfort to Jin and instead added even more pressure upon him.
Normally it would have been fairly easy for him to memorise the script since Michael had tasked him to cover only a single scene which was barely a full page.
However, under the constraint of time, pressure bore upon his mind and he started getting more and more nervous with the passing of each second.
He could only resort to speaking the lines again and again to memorize them.
He did that for the next 15 minutes under the constant gazes of Michael and Tyler who looked at him with a weird expression.
'Is it so tough?' They both thought when they saw him repeating his lines.
