This makes me respect Meera way too much. Cameras are already placed all along the path which means that the actor has to maintain expressions, listen to the director's instructions, remember n follow the choreography of the scene and do every action that comes under these keeping in mind that it's pure mud she is walking on. It's slippery, dirty and dangerous.
On top of that Meera was improvising the action when she found a stone saying that she will jump from it.
The director was repeatedly asking her to jump in the mud to give that dramatic experience. Not just once but many times this scene got repeated. Wow!! Kudos to this girl.
She actually fell in the mud with her face in it. This girl has all my respect now.
