Continuity: It's a great new car Starsky gets at the end, just like his old one...even down to the licence plate, which is 537 0NN, proving the same car's used both times. You see the original's plate when he crouches down while being shot at, and the replacement when it takes that jump right at the start of the credits at the end. Same both times.

Continuity: After Hutch has played his song, his guitar is hunched into his armpit in wide shots, but lower down in close-ups.

Continuity: When Hutch tackles Starsky to the ground after his gun goes off in the disco, Starsky's badge falls to the ground beside his head. Hutch grabs it and holds it up, telling people to calm down, but when the shot returns to Starsky the badge is still there next to his head.

Revealing: Towards the beginning of the movie Starsky and Hutch are driving the Torino and they get a call over the police radio. There is a shot of the car pulling a u-turn on a bridge from above. Look at the bottom of this shot, you can see tire marks where they practised the move before.

Continuity: When Starsky and Hutch first visit Reese the drink that Hutch is given changes from being in his hands to being on the table next to him several times.
