"Phantom" is the directorial of Kabir Khan, who has explored the aftermath of the 26/11 Mumbai terror attack in the movie.
While they shot several action scenes, Katrina said "only Saif was given machine gun in the movie".
She said the "best shooting happened in Lebanon... which is where you see the tents and guns and the whole portion where Saif is shooting the machine gun and I have my gun. That was definitely the most exciting and funniest portion."
