Karan Johar originated Varun Dhawan and Alia Bhatt with 'Student of the Year' in 2012 but the fresh star says it is not necessary that they sign every movie with the director-producer Karan Johar. Varun and Alia's upcoming movie 'Badrinath Ki Dulhania' has been produced under Johar's Dharma Productions banner. 'It got a year-and-half to grow up with 'Badrinath Ki Dulhania'. They did not sink for just anything. They both are in a powerful place in their career, they will not do a movie just for the cause of it, no matter who is executing it' Varun said in a conversation there. 'They share a very healthy relationship with Karan Johar. If they don't admire something they can respond no to him. He has held that option open. But Karan will never suggest them anything that is not great enough' he said. The 29 years old Bollywood's sensational actor appreciated Alia for her dedication towards her work. 'She (Alia) won't fall for anything. She wants to be convinced about everything is excellent and not only with her but with everybody else in the movie. There was one scene that they had to re-shoot as she was unfortunate. She puts her best foot ahead.' Varun is confident that the audiences will surely like 'Badrinath Ki Dulhania', which is a romantic drama inclination in the heartland. He then said that 'Their director Shashank Khaitan is a little town and his way of understanding romance and the love story is very distinct from the way an urban person like him or she would see it'. According to Varun, 'Humpty Sharma Ki Dhulania' was a success because it had a lot of heart and people attached with the sincerity of the love story. The actor said if the sequence does well, it will be only because of the emotional combination of the people with the two personalities. The romantic-comedy is set to publish on March 10.
