MMKR: In the first night scene, Kamal's Kameshwaran gets up from the bed in shock on seeing Avinashi and paati. And then he is searching for his pant pockets to dip his hands in, when he is wearing a veshti. Odd for someone who has worn veshti all his life to be doing this.
Aboorva Sagotharargal: When 'Crazy' visits Kamal's mechanic shop to take delivery of his vehicle, Kamal glances at the camera for an instant, moves 'Crazy' to the correct angle and continues the conversation.

Both pretty obvious mistakes and quite surprising coming from Kamal.
