Sonu is in Punjab for the extensive shooting schedule of "Paltan".
"Captain Amarinder Singh is a great guy and he has contributed a lot to the betterment of his state. Since the schedule was getting over, I thought it would be great to make the 'Paltan' team feel special by organising a lunch with sir," Sonu said in a statement.
"He is a well-read guy and has hosted us well. The entire team had a good time interacting with him," he added.
The film is being directed by J. P. Dutta, known for war-themed films including the National Award winning "Border". "Paltan" also features Arjun Rampal, Gurmeet Choudhary, Siddhanth Kapoor and Luv Sinha.
