However, Abhishek had sent a video message to the event, thanking everyone for participating and supporting.

Unfortunately this was not shown during the event, which apparently has browned-off Big B.

Big B upset Abhishek was sidelined
Amitabh Bachchan is disappointed that his son Abhishek had been sidelined in the Earth Hour event at the capital.

An upset Big B posted in his blog, “A few hours before the show was to start, apparently the audio visual featuring Abhishek has been asked to be removed and banner posters bearing his photograph as the ambassador have been stopped from being displayed!!”

Earth Hour was a huge success
After working hard to promote the Earth Hour by telling citizens to turn-off the lights for one hour, Abhishek felt upset that he couldn’t be present at the function, as he tweeted, “I was to be at the India Gate function (Saturday evening) being the ambassador, and all, but prior shoot commitments would not allow me. I'm tucked away in Goa.

"I had sent a video message for all at the event, thanking them for their participation and support, but for some reason that couldn't be shown.”

He posted, “I hope we never have to celebrate another Earth Hour! I hope we can reverse the effects of global warming! I hope we can spread the message of a greener tomorrow.”

Irrespective of him not being present in the event, it turned out to be huge success, “I'm told that the Earth Hour was a huge success. Well done guys. You'll have done a wonderful job in spreading the news... I believe the function at the India Gate was also very nice and well attended. Kudos to the team at WWF for pulling all this off,” Abhishek further tweeted.
