Airtel 4G Girl Sasha Chettri is going to make her debut in Telugu film under Sai Kiran Adavi's direction. Speaking about her debut, Sasha said she liked the story of the film which has cut across the language barriers. Her shift from Ads to movies was made possible by Mahesh Gangimalla. The only difference between doing an Ad and a film is in terms of energy and time, she opined. Her favourite heroes in Tollywood are Vijay Devarakonda and Mahesh Babu. One has to believe in oneself to realise their dreams, she suggested the new comers.
