Sushant Singh Rajput almost got a surprise liplock while shooting for his film, 'Byomkesh Bakshi'.

Director Dibakar Banerjee had only told him that there will be a peck, but co-actress, Bengali star Swastika Mukherjee was informed about the full-blown kiss.

This ploy was because Sushant is expected to have a shocked expression on screen and the director naturally got just that.
