During the brawl in the pub, Bodie suddenly acquires some kind of t-shirt/vest top underneath his clothes, towards the end of the scene...to stop his trousers falling down, perhaps?!
When Culbertson is waiting for Barry Martin in his flat, you can see smoke rising by the lapel of his jacket - before he has even sparked up!
When Cowley goes to view Alex Bolt's corpse at the mortuary, you can clearly see the actor playing Bolt swallow!
Some of the camera crew can be seen reflecting through one of the glass windows that Doyle is walking past whilst at the hospital.
When Bodie and Doyle are giving the villain a lift, there seems to be few problems with the scene sequencing.
Bodie and Doyle are stopped for speeding outside some houses. But this miraculously morphs into a row of shops by the time they drive off again.
Watch Doyle closely when he arrives in the hotel room and takes off his shoulder holster with the gun inside.
Bodie answers to the 3.6 call sign, despite being known as 3.7 in every other episode!
Watch out for the invisible rainstorm that seems to occur outside the Festival Hall in between the kidnap scenes, during which the pavement alternates between dry and wet.
A microphone can be clearly seen reflecting in the mirror during the "Running all the way, sir!" scene.
Bodie seems to have lost the side-mirror off his Capri during the scene where he goes to make a call in the telephone box.
Agent Bodie's full name is given as William Andrew Philip Bodie — the only time it is used on the show.
We very much doubt this kind of 'trial' would get past a real Court of Law!
The conclusion culminating in Parker's attack is an all-too convenient escape route.
This was the first episode during which any of the operatives' call signs were mentioned, although there are some mix-ups. Bodie is 3.7, and Doyle is 4.5.
Whilst searching Brownie's boat, Bodie finds a round supposedly belonging to the laser gun, but it is actually the wrong size.
Not a goof as such, but with reference to Cowley, it seems a little odd that in the last episode, Look After Annie he had a somewhat less than favourable reaction towards Annie's black friend Stanley... Or maybe that was just because he was hoping to have his way with her again!
The way Dinny has been working for Mr Miller for all this time and has never even met him - thus not realising that Miller himself is black! Initially, a slightly strange turn of events but when you discover the reasons behind it - Miller using Hulton's Empire Society to run his tenants out of town - then the situation becomes clearer.
In the final scenes, Bodie and Doyle are seen taking Annie to Gatwick Airport, although many of the previous airport scenes from season one episodes were shot at Heathrow.
There is a scene of Doyle passing out in the van, but then the camera switches to a shot from Stanley's position, during which we see Doyle slump over for a second time! Bad editing or ultra-bouncy seating?
