While Sanjay Gupta's Acid Factory first look launch was a rocking event for everyone, one actor from the film sulked at the party and that was Gulshan Grover.

Acid Factory is a multi starrer starring Manoj Bajpai, Irrfan Khan, Fardeen Khan, Aftab Shivdasani, Dino Morea and Dia Mirza apart from Gulshan Grover.

Almost every single actor and crew member connected to the film was present there. When the event proceedings began, the emcees of the event actor Rohit Roy and singer Manasi Scott heaped loads of praises on all of them excluding Gulshan Grover who has a very significant role in the film as he plays the role of the uncle of the main leads.

The Bollywood bad man known for being a thorough gentleman off screen was visibly upset over this.

So when it was his time to speak he vented out his frustration in a sarcastic manner in front of the media and expressed his displeasure to Sanjay Gupta. Gulshan has worked in many Gupta films right from Aatish to Kaante and certainly the pain could be understood.

We wonder why Sanjay Gupta continues to rub his long associated people the wrong way. First Sanjay Dutt then business associate Dharam Oberoi, then again last weekend there was news about Gupta and Irrfan Khan having payment related issues and now this live example!
