The gorgeous actor was romancing her hero Sivaji Dev enacting for the duet that was been canned by director Shyamalan from an adjacent boat.
While this was happening, a giant boat had come in the opposite direction at jet-speed and the film crew was taken aback.
Despite the earnest efforts of the boatman to steer his boat clear off the giant boat, it fractionally crashed into the edge of the boat that had the actors.

That certainly was One adventure for Mithra.
