Emma (2009)

Season 1 generally

Continuity mistake: Harriet's bedroom appears to be in Hartford rather than Mrs. Goddard's school. In the scenes shot inside Harriet's room, we see that she has a distinctive window that is a square set within a circle. In shots of the exterior of Hartford, that window is visible, while shots of the exterior of Mrs. Goddard's show a building without features that would have windows of such style.
