When Steve jumps down off the wall inside the villain's compound and the picture switches to a closer shot of him landing, a large twig is visible lying on the wall's cement footing, together with some dirt and bark fragments, none of which were there a moment earlier as Steve was sailing down off the top of the wall; obviously this is action-loosened debris that was left by several previous attempts to get a good shot of Steve landing.
The multi-paned window that Steve opens to enter the castle has a noticeably thicker frame in the "outdoor" shot as compared to the frame on the "indoor" shot.
It is obviously a clear winter day in the villain's area; there is a lot of snow and the ground is brown and the trees are bare during the first part of the final chase scene, yet the later portion of the chase is through an area of lush forest and thick green grass, and with a light late-spring rain falling.
The blue car is undamaged when Steve kicks the edge of its rear undercarriage and flips it over on its side, yet the front passenger's door clearly has a massive crushed dent as the car rolls over for the first time (it's still otherwise undamaged, so the door couldn't have gotten bent from rolling) and goes over the cliff.
After Steve gets off the pay phone at around 16:25 minutes in, when he jumps down off the balcony, you can tell it is an obvious stuntman.
The license plate on the blue car chasing Steve at the end of the episode shows the reverse picture with the numbers backwards '5(symbol)7-903'
At around 35:50 Steve fights a guy in a white track suit. After Steve throws him you can see the is a line that is pulling him across the snow as he glides away from Steve.
Rudy and Steve escape from the estate and are pursued in a high-speed chase on soft and muddy dirt roads, but the sound effects are those of tires squealing on asphalt.
When the non-bionic Yano rips the lamp post out of the ground and clubs Steve with it, we hear the bionic sound effect.
At around 28:30 Steve is handcuffed to the wall. The cuffs they used do not have a ratchet system but a bolt. The sound is from a set of handcuffs the police normally use with a ratchet system and not a bolt.
All cars shown in the episode have license plates from Styria ("St" followed by 4 digits in the show) although the story takes place in the district of Salzburg. Until the late 1980s, license plates from Salzburg were defined by an "S" followed by one to six digits.
At one point Col. Steve Austin asks a pretty cafe waitress at small town in Austria how to say a certain phrase - "in Austrian". Austrians speak German.
The waitress's translation of Steve's phrase, "Stop looking at him and get over here right away," is inaccurate. "Beobachten Sie jetzt nicht und komm sofort heraus" translates to "Don't observe him now, and come out of there right away." (Steve's phrase would translate more closely to: "Hör auf, ihn anzuschauen, und komm sofort heraus.") Moreover, the waitress's translation mixes formal ("Beobachten Sie") and informal ("komm") verb forms, which a native German speaker would not do when addressing only one person, as Steve intends to do.
