Victor's mother says she has "taken up knitting" and shows what appears to be the beginning of a onesie for a baby. The object knitted is more of a silhouette than a three-dimensional object. When sewing, silhouettes are often cut out and sewn together. However, with knitting, where one creates the cloth as one goes, it's easier to create the three-dimensional object in situ. This is certainly the case with the legging section of the onesie (leggings being, essentially, long socks, which are simple to make in three dimensions). While it's not impossible to make two silhouettes and seam them at the sides, it seems counterproductive.
(at around 20 mins) When Rose first goes into the restoration department of the museum she startles Gerry and he flinches, leaving a dab of paint on the left-hand side of the man's forehead just below the hairline of the painting he is working on. In the next camera angle he seen removing the dab with a cotton tipped stick from the right-hand side and there is no paint mark on the left side.
When Victor and Rose enter Victors home, they begin to talk about Victor's mother, but when Tony walks in with the Cat, the cat is facing front (Towards Victor) in the first shot, then in the second shot facing Tony, and the cat then puts it's arm over Tony's shoulder in that same shot, but again seconds later in the 3rd shot of Tony, the Cat is facing front again in the same position as the first shot.
