“Udta Punjab” actor Diljit Dosanjh is all ready to show his patriotic side as Sajjan Singh in the trailer of his upcoming Punjabi film “Rangroot”, which is based on First World War. The movie pays a tribute to the sacrifice that the Indian Army made during the World War I. The trailer highlights the underlining conflict of a soldier, who is away from home and fighting a war for people, who are trying to destroy the mother land. Must say, Diljit has done an excellent job. Apart from this Dosanjh will next be seen in Bollywood film “Welcome to New York” in a quirky character, which also stars Sonakshi Sinha, Karan Johar, Lara Dutta Riteish Deshmukh and Boman Irani.
