A source close to the actress says, "Katrina didn't take the posters; it was Siddharth Anand who showed the film's posters to Aditya Chopra as they are good friends and Siddharth wanted the YRF head honcho's inputs."
Another source close to the director says, "Siddharth considers Aditya as his mentor; he is known to have sought Adi's approval for his films' creatives on several occasions. Adi loved Bang Bang's posters."
While Katrina remained unavailable for comment, director Siddharth Anand confirmed the story. "I'm blessed to have the access to him; it's great that I can seek his opinion.
I regularly take his advice on my film's trailers or posters - much like my son shows me the work he's done in school!
Siddharth Anand
I had showed Adi the first trailer and the first cut of Anjaana Anjaani, so yes, I have shown him the posters of Bang Bang as well," he said.
