Megastar Amitabh Bachchan has shot a commercial for a new mobile video sharing application called `Wacau`, which will enable actors to put up their videos and get instant feedback from their fans.

The application is said to be created by Big B's digital team.

"No... It's not an ad, shoot for a mobile... That is to come later.. This is for the new App, that we and our digital team intend to launch called 'WACAU',` the 72-year-old wrote on his blog.

"Where celebrities shall be able to put up videos to connect with their fans and get back responses too.. Will be fun...," he added.

Amitabh, who was last seen in filmmaker Shoojit Sircar's `Piku`, also posted some of the photographs from the shoot of the mobile app.

He will next be seen in `Wazir`, which also stars multifaceted Farhan Akhtar.
