Sharman Joshi recently shot with a Hollywood-based choreographer Simon Lind for an ad campaign. Simon is the name behind the tap dancing penguin, Mumble, in Happy Feet.

In the commercial shot in Australia, Sharman will also be seen getting jiggy with a penguin. The actor was supposed to wear a green T-shirt.

But the crew was in for a shock on the sets as everything was to be shot with a green background, and Sharman's t-shirt was merging with the background.

The star then simply borrowed a white tee from a crew member and shot for the ad. Later, the t-shirt was converted to green using special effects.
