Kriti Sanon believes acting is a tricky profession as one has to "switch on and off" from their real-to-reel emotions every now and then. The actor, who is looking forward to Arjun Patiala, says a performer maybe going through tough times in their life, but when in front of the camera their real emotions should not reflect on-screen.

"As actors, we can have tension and stress in our life too and when you work on a film like this ('Arjun Patiala') you have to switch off from it completely and turn into a person who is having fun and is cracking jokes. It can get tricky. While filming for 'Luka Chuppi' I was a little messed up in my personal life but I had to get my comic timing right. It is important to switch on and off as an actor," Kriti told PTI.
