(The) Harry Potter actress was a new element in the work of Pensa & Rocca CINE. Because of its quality superstar, had a strict protocol which must be realized in terms of security. Always surrounded by his team, was also necessary to have permanent cars and a specific hotel, besides taking care that no one approached within 150 meters of the shooting.
During that Watson was in Buenos Aires, had no more contact with the film crew. "Almost nobody interacted with her entourage had seeped you. To chat and talk not given, was not allowed to take pictures and the few photos that she took the administered and rose to its website, "adds Rocca.
With Brühl, the experience was totally different. Spanish mother and resident in Germany and Barcelona, the actor was handled with Spanish and prepared to engage with people. It was something else, had no security, he moved with absolute normality and photos drew with people.
That lack of interaction with the crew doesn't sound nice.
Anyway, I can't wait to see the film.
