During the wedding scene, Victoria hands off her bouquet to a bridesmaid as she is about to take her vows. The camera then cuts to the archbishop, then to Albert then to them both and Victoria has the bouquet back in her hands again. The next time the camera cuts to her, the bouquet is gone again.
The CGI of the location and exterior of Schloss Rosenau in Coburg looks nothing like the real castle that can be seen in Germany.
The depiction of Schloss Rosenau is inaccurate. In reality the castle is rather small and situated on a hill surrounded by an English garden.
