Abdul Rashid Salim Salman Khan is an Indian film actor, producer, occasional singer and television personality. In a film career spanning over thirty years, Khan has received numerous awards, including two National Film Awards as a film producer, and two Filmfare Awards for acting.
Salman Khan replied to this in a different way. He said that "I like Mahesh Babu very much in the South. I also eagerly wait for his films. I am very excited to see every single film of his. If I see Mahesh Babu's I am also a fan. And as far as copying the matter is, I have remake a film of them and maybe I copy their style sometimes too ".
Mahesh Babu called the savior of Salman Khan's career because Sallu's career has almost ended by the year 2009. Mahesh Babu entered his life to save his career. Don't take the literal meaning. His movie came to his rescue and that movie is WANTED. Actual name is POKIRI starring mahesh Babu and Ileana D'Cruz. In hindi Ayesha Takia is the heroine. From then his career took of and he's known as the most bankable star in Bollywood. He's given the maximum number of all time blockbusters to Bollywood quite a number of post 2009 period. Since then he's had just one disaster (main aur mrs.khanna) and semi hit (jai ho).
By this we can clearly say Mahesh Babu indeed saved Sallu's career.
