I don't know why all Bollywood stars act as salesmen

B-Town biggies pull out all stops when promoting their films. Here's a list of the capers...

During his recent visit to Mumbai for a special screening of Robot, Rajnikant quipped, "I don't know why all Bollywood stars act as salesmen when their film is getting released."

The South sensation obviously does not subscribe to actors going on an overdrive and being in the media glare on the eve of the release of their movies.

For all B-Town folks, it begins with the music launch of the movie in a five-star hotel or on a music-based reality show on television.

Rajni himself had made an exception by being present for Robot's music launch in Mumbai at a Juhu five-star.

He had stated at the event that he never attends any filmi dos and was breaking the rule only once for director Shankar.

For most Bollywood stars, promoting their project means interviews with TV channels, appearing as a judge on reality TV shows to talk about the upcoming flicks, public appearances at malls and events, blogging or even joining Twitter, like Shah Rukh Khan (MNIK) and Aamir Khan (3 Idiots) did.

More recently, technologically-challenged director Farah Khan did it for her upcoming film Tees Maar Khan.

Here are examples to the extent stars go to, to promote their film's release...

Ranbir Kapoor had a mock marriage with one of the contestants of a reality show during the Anjaana Anjaani promotions. Salman Khan appeared on Entertainment Ke Liye Kuch Bhi Karega as part of Dabangg's promotions with his pet dogs. He is very possessive about them.

Abhishek Bachchan wore the reading glasses from Paa to every event for weeks before and after the film. Now John Abraham is doing the same for Jhootha Hi Sahi.

Shahid Kapoor and Genelia D'Souza spent a night together in a car parked at Kamalistan Studios for Chance Pe Dance as the movie was about strugglers.

Aamir Khan travelled incognito throughout the country during the promotions of 3 Idiots and people had to find him, keeping the story in mind (he goes missing in the film, while the other two 'idiots' look for him).

Raat Gayi Baat Gayi had condoms, aspirins, toothbrushes, toothpaste as part of the media kit! Shah Rukh Khan took to Twitter during My Name Is Khan after buddy Karan Johar told him to. He wanted SRK to communicate with his fans and keep them updated about his daily routine.

Dulha Mil Gaya actor Fardeen Khan became a groom again and led a marriage procession starting from Lokhandwala to an Oshiwara mall.
