Actor Kartik Aaryan revealed he lied about knowing how to swim to 'Chandu Champion' director Kabir Khan, adding it took him 1.5 years to learn it. "In reality...I could only do enough to keep myself afloat," he said. "One and a half minutes of lying cost me 1.5 years," Kartik jokingly stated. The film was based on ex-swimmer Murlikant Petkar.
