Here are 3 important trailers that are likely to release with Shivaay and Ae Dil Hai Mushkil

Karan Johar's Ae Dil Hai Mushkil and Ajay Devgn's Shivaay are headed for a colossal box office battle and the industry is in the process of making the most of it. Rumour has it that Dangal trailer will be attached to the prints of the said films.

"Team Dangal is in advanced talks with Team ADHM and Team Shivaay. So far so good," a source informed SpotboyE. The move is well-calculated because the reach of both these films is expected to be wide.

Interestingly, this isn't the first time that films have been in news for wanting to attach their trailers to ADHM and Shivaay. Dear Zindagi and Kaabil teasers too may be out with the mentioned releases.

"Rakesh Roshan and Sanjay Gupta have plans to launch the theatrical trailer of the much-awaited film during Diwali this year. Reportedly, the trailer will be attached to the prints of Shivaay and Ae Dil Hai Mushkil - thus resulting in wider reach for the film," a source told Catch News.

Why is "ADHM" and "Shivaay" crucial for both Karan and Ajay?

Shivaay is Ajay's second film as a director and Karan is going behind the camera after a gap of six years, which is why both these films need to work at the ticket-window.

What else do we know about the clash?

The films are competing with each other and are no longer in hiding about it. Three days after Bolo Har Har Har song was released online, makers of ADHM uploaded Bulleya on YouTube. In this round, ADHM has overshadowed Shivaay by garnering over 13 million hits on the video-sharing site, whereas Bolo Har Har Har managed to cross the 8 million mark in 10 days.

Action-thriller Shivaay stars newcomers Erika Kaar and Saiyyeshaa Saigal. Ae Dil Hai Mushkil is a romantic-drama featuring Ranbir Kapoor, Aishwarya Rai Bachchan, Fawad Khan and Anushka Sharma in the lead, with a cameo from Shah Rukh Khan.
