Most of the highly paid actress will take more money from the producers and will not support for publicity Trisha and Nayanatara are the best examples. But the actress like Kajal and Tamanna will support the movie even though it is flop. As Kajal promoted the movie sarocharu. Tamanna now promoting the movie Tadakha, recently in one interview tamanna said "we have to take care of the film which we acted, if we dont support or dont promote why to act in that film?".
So other actress have to learn from tamanna. It will be good to the industry.
