Sundeep Kishan and Lavanya Tripathi's A1 Express is an upcoming Tamil-Telugu bilingual sports drama based on the sport Hockey. Sundeep is also co-producing the film, which happens to be the first film based on hockey in the South. Very recently, the film unit headed to Mohali to film the climax and happened to know that the stadium they choose has a special significance. It is the same stadium where Shah Rukh Khan shot the climax of Chak De 13 years ago. The film also had another similarity with the SRK starrer as they shot with the hockey coach who had acted in Chak De. Sundeep, who is a big fan of MS Dhoni, will be seen wearing Jersey No: 7 (same as Dhoni's Jersey's number).
