Two Bollywood stalwarts like Big B and Aamir Khan rarely clash at the box office. Amitabh Bachchan's Bbuddah Hoga Tera Baap and Aamir Khan's Delhi Belly are all set to release this Friday. Both are drastically different films, but interestingly have similar marketing and publicity techniques.

Both have cashed on the burning topic 'the age limit for drinking in Maharshtra'. While Big B tweeted about it incessantly, Imran Khan announced his plans of filing a Public Interest Litigation.

Both have relied on the strategy of abuse or not to abuse. While DB has 'in-your-face' songs with abundant use of double meaning words and expletives, AB's Bbuddah has beeped the abuses.

Also, both Aamir and Big B have turned item boys for their respective films.

With so much efforts being put in by both parties, it would be fun to see who wins this BO race on July 1.
