Sayani Gupta posted this selfie with Ayushmann.

'Today was a true test of my love for my craft', Ayushmann writes. 'We are in the middle of shooting Article 15, being directed by the super talented Anubhav Sinha. Yesterday, we had a challenging day - a shot required us to enter into a swamp and do a gripping scene. We realised that the swamp was filled with leeches only when we were in the middle of the shot! I would like to salute my brave team of investigative officers (it's an honour to act with these talented actors) for finishing the scene despite a vicious leech attack! @anubhavsinhaa hum aapke liye khoon bahane ko tayaar hain. #Article15'.
