When the Torino is chasing Callendar's car, right as he sees the truck pulling out, you can see the Torino has a smashed back fender and side damage. This is seen before the Torino near-miss with the truck.
Possible blooper: When Starsky and Hutch pursue Callendar's car, the back left-side light on the Torino gets smashed. It's not quite clear exactly when this happens – the car swerves to avoid a truck pulling out, and it could be presumed to happen then. In which case, in the shot of the Torino narrowly missing the truck, the light can be seen to already be smashed before the car comes anywhere near the truck!
However, just before the shot of the Torino just missing the truck, during the shot of Starsky turning the steering-wheel, there is a smashing sound, maybe suggesting that maybe the light was broken then.
On the closing credits, the usual 'Guest Starring' caption is missing before the guest cast billings. It is also missing on Part II of the story.
Although the feature-length episodes also exist in two-part versions, this is the second of two stories originally shown as a two-parter (the other being the second season's 'The Set-Up'). It quite probably also exists in feature-length version.
In the United Kingdom, this story was the most watched episode of 1977, clocking up 16.7 million viewers when it was first broadcast on Saturday 10th December (BBC 1, 9:05 p.m.). (It's not clear whether this was Part I or Part II of the story).
