This comes after his last appearance on television, for the finale of Indian Idol 6, accompanied by his Barfi! co-stars Ileana D'Cruz and Priyanka Chopra.
Hitler Didi has nothing to do with the reviled dictator of Nazi Germany but is about a young lady who has to provide for a large family, and becomes a strict disciplinarian.
It may seem like the program is rather inappropriately named, but the name 'Hitler' has somehow managed to enter the Indian consciousness as a person who is excessively strict - and not as the image of a man who caused the genocide of millions of people.
In picture: Ranbir, in character as Murphy from Barfi!, wanders on to the sets of Hitler Didi.
