Revealing mistake: When Glen and Glenda walk up to Jennifer and kiss her on the cheeks, Glen noticeably "shifts" unnaturally when they lean. Later in the shot, they "glide" somewhat as they start to walk out of frame. Since Lachlan Watson played both characters and filmed them separately, it looks like they had to digitally shift Glen around in the frame a little bit here and there. It's easy to miss, but if you know when to look, it's noticeable.
