"We did our part. Make feasible the filming of Dawn in Rio P / bring investment, promote the city and give more realism to the film."
"We can't turn something positive into a negative. Having BD film here is better than not, right? So let's celebrate.
"About Dawn ... Safety standards have nothing to do with the fans. And it is normal w / a movie this size. Will be five days of intense work."
Added: No fan event, just filming.
"Q We want everything runs smoothly and on time. This is a film d, d not a promotional tour. The conditions are determined by producers" via gossip_dance
I think the journalist was not informed that the Isle Esme scenes are the honeymoon scenes and does not include Taylor's character. lol
Please take note that nothing is definite about the dates, so this is labeled under rumored info.
Thanks Nina. :)
