Advani on Wednesday (16 May) tweeted: "An association that began way back in 2005. I am so thrilled to be collaborating with Ritesh Shah [screenwriter] once again after D-Day (2013) [and] Airlift (2016). We have worked for three years on this story and are so happy to have John Abraham help us tell it. Batla House."
