Continuity mistake: When Lindsay has just returned home and is placing the flowers she has bought into a vase, we see her remove the flowers from the shopping bag and place them on the kitchen worktop. A few shots later, the flowers have moved back into the bag and we see Lindsay remove them again.
Continuity mistake: In the scene where Michael has just taken Lucille number two to Tobias' new club, the shots are obviously taken on different occasions. The collar of his jacket goes from misaligned to correct, his hair goes from ruffed to "done" and the lighting goes from hard and sharp to soft. (00:18:50)
Revealing mistake: When Michael is talking to George Michael, Oscar, Buster, and Tom Jane about the house they are about to build (and what they all want out of it), it is clear in the wide shots showing all five that Tom Jane is not present; the person standing in for him has a completely different haircut and wears glasses. They try to hide it but it is obvious at several points. (00:14:15)
