Continuity mistake: The windshield of Morey's car shatters when they storm Considine's gate. The glass is spidered and sagging, but all there - until a few shots later, when suddenly more than two-thirds of the windshield is missing altogether. No one had time to knock the glass out.
Continuity mistake: Laura grabs her day planner and closes it. She then clips a pen to the top, stuffs her pocketbook under her left arm and begins to walk out. As she passes Murphy, she flicks the planner at him with her right hand. The pen goes flying out and a moment later, a woman's voice sounds in surprise, as if she just got hit with the pen. The pen flip may be deliberate, but it doesn't seem like it, as Murphy doesn't react at all. Also, as Laura continues to walk, she puts the planner, still in her right hand, over her head as Steele chases after her, calling her name. Cut to the next shot from the front; Steele is still calling her name, but now the planner is in Laura's left hand and by her side and her pocketbook is now under her right arm.
Continuity mistake: Season 2 "Hounded Steele" - At the end, just after Steele kicks the gun away from Blalock, Laura runs up to them. The collar of her coat is turned up but the lapels are flat. The shot switches to a close-up and now the coat lapels are standing straight up.
Continuity mistake: During the last scene of the opening credits, they are robbing the museum and Steele and Laura slide across on a zip line. When Steele catches Laura, she flops over his left shoulder. The shot changes and Laura is instantly upright so she can slide down Steele's body while looking at him romantically.
