Continuity mistake: When George and Dr. Grace are in the cold storage room, George eats a noticeable amount of his snowball. When he hands it back to Dr. Grace to leave suddenly, it is back to being untouched.
Continuity mistake: At the end of the previous episode Murdoch has a ring with a dark blue stone, but at the start of this episode he takes out the box and the ring has a dark red stone.
Continuity mistake: In the 1st 5 or 6 seasons the inspector introduces himself as Thomas S Brackenreid. Later he becomes Thomas C Brackenreid.
Continuity mistake: The snake that bites - and therefore kills - Prof. Greenwood (and which is later found by Crabtree and Higgins) has nothing to do with the one Dr. Bajjali puts on her shoulders or the one Dr. Grace dissects later on, despite they are supposed to be the very same snake. The first one is seemingly a King cobra, while the other one resembles a Python (which is not even venomous). The visual difference is totally obvious.
Murdoch Ahoy - S7-E1
Continuity mistake: Amy was just rescued from a flooding hold, but when she's being helped onto the life boat her dress and hair are completely dry.
The Ministry of Virtue - S14-E6
Continuity mistake: Around the middle of the episode, Hart and Carmichael walk down a street with ice cream cones in their hands. When they stop for a brief face to face discussion, the ice cream in the man's hand keep changing from full portion to half-eaten and vice versa as the camera perspective switches back and forth.
Murdoch and the Temple of Death - S8-E10
Continuity mistake: When Murdoch and Dr. Bajjali reach the grail chamber, the detective tosses a coin on the pedestal to see if it's trapped. The coin triggers the firetrap and falls to the ground. Murdoch then throws another coin which ends up resting on top of the pedestal, next to the fake grail. Now, when the detective removes the pedestal cover, there is a quick cut when both coins can be seen on the top of it, despite that the first one is supposed to lie on the ground.
Continuity mistake: After the failed attempt to stop Mr. Dilbert's bleeding, the ambulance attendant collects and takes away all the bloody rags they used for hemostasis. Still, the very next cut shows a whole pile of rags on Mr. Dilbert's body. To make the mistake even more evident, both his shirt and these rags are all clean with no blood on them. (00:42:35)
Continuity mistake: When Murdoch and Crabtree arrive to the fairground to apprehend Agnes, they lean their bikes against the "annual fair" banner stretched on a handrail. The camera shows the detective and the constable from behind, making visible that the weight of the bikes make the banner to ruck down significantly. However, when the next cut shows them frontwise, the banner is in neutral position. (00:40:30)
Continuity mistake: Shortly after arriving to the crime scene, Murdoch instructs Crabtree to collect the fingerprints of the asylum patients - but the women in the institute were arrested before (most of them by Murdoch himself) so their fingerprints should've been collected already. It's pointless collecting them again.
Bend It Like Brackenreid - S10-E7
Continuity mistake: At the beginning of the episode, some of the main characters are spectating the ongoing football match. Look at Dr. Ogden: the position of her hands - therefore the way she is holding her bag - keep changing cut by cut.
Glory Days - S8-E3
Continuity mistake: Towards the end of the episode, during the final shootout, Murdoch ambushes an armed bad guy in the attic and jumps through the wooden wall with him. As they fall down, Murdoch's trademark hat spectacularly flies off his head, but in the next overhead cut - showing him and the bad guy lying on the ground - the hat is on his head again.
