From intensive physical training to cutting off oneself from rest of the world, present-day actors are going to extreme lengths to prepare for their roles, much before the cameras start rolling and the director shouts out 'action'.

Tusshar Kapoor and Aftab Shivdasani (right) recently met porn stars in Bangkok to prep up for their roles in the third instalment of 'Kya Kool Hai Hum'

If Ranveer Singh's self-imposed isolation for 'Bajirao Mastani' and Randeep Hooda-Alia Bhatt's non interaction during 'Highway' was not enough, take this: porn talk for preparation. Tusshar Kapoor and Aftab Shivdasani, who play porn stars in the third instalment of 'Kya Kool Hai Hum', recently jetted off to Bangkok to meet some such real entertainers! Tusshar is also incorporating a part of their lifestory in the film to add to its "authenticity".
