Varun, who was just seven-years-old during the making of Judwaa, told that Salman asked him to say 'Salman bhai' instead of uncle.
"I went for trial (show of Judwaa) and called him Salman uncle he got very upset. He told me 'I will slap you if you call me that, call me Salman bhai. I don't care if you are David Dhawan's son I won't allow you inside theatre if you call me uncle,'" media quoted Varun as saying.
Before Varun started shooting for the Judwaa2, he spoke to Salman. He told the press that he didn't want to disappoint Salman.
"We all have spoken to him it's a personal thing. His blessings are always there. I don't want to disappoint him (Salman), them (Sajid Khan and David Dhawan) and the audience," said the 29-year-old actor.
Judwaa 2 is directed by his father David Dhawan and Varun reprises Salman. The shooting for the film began last week and Salman is also expected to do a cameo. The 51-year-old actor will feature as 'godfather gunda' to the judwaa Varun brothers.
Varun told that Salman has send him a box full of jeans which he can wear for the role of Raja in Judwaa 2. The original Judwaa featured Salman Khan as separated brothers Raja and Prem Malhotra opposite actresses Karisma Kapoor and Rambha. In Judwaa 2, Varun Dhawan has been casted opposite Jacqueline Fernandez and Taapsee Pannu.
