Vikram known for his penchant for doing different characters, has always been dreaded onscreen, to compete with. Forget his contemporaries even his co-stars are carried away by his versatility and try to give out their best in his presence. This could be, because of two main reasons. One is to stay in lime light along with him and the second is to give their best to strike a balance.
When such is the case, if one asked Vikram whom he would feel the toughest to work with. The actor first admits that he had the best chance to work with the best actors of his times. But if you are persistent enough on the question for him to select, then chirps comes the reply. For him he finds it, too difficult to compete with Jyothika, Anushka and Tabu. That was really great of the star to admit. On the other hand the stars say that it is the best way the actor could compliment them. The trio univocally must be feeling that being an artist with indomitable energy levels, Vikram's verdict is a real compliment for them to put up even better performance in future.
However Jyothika is no more into acting and has turned a home maker after marrying Surya. While the other two, are in the reckoning and with this compliment are sure to give their shot in the roles that they adore. (With inputs from internet-AW AarKay)
