Continuity mistake: When Alice falls through the "ceiling" in the round room there is a hole created by her coming through. The room rotates 180° so the ceiling becomes the floor. Through some miraculous occurrence the hole in the floor is no longer there. (00:13:27 - 00:13:55)
Continuity mistake: When Hamish proposes to Alice the scene goes back and forth from them to the audience. In the first shot of the audience there is a bearded man behind Imogen's left shoulder. In the next shot he is standing some steps to the left behind a post. The next shot he is back behind Imogen's left shoulder. In Imogen's closeup he is now standing behind her right shoulder and when Alice runs off he is back behind her left shoulder. (00:10:38 - 00:12:02)
