Crunch Time - S4-E16
Continuity mistake: At the end of the episode, Steve and John Sears are behind the table and one of them is about to be voted out of the fraternity. Pay attention to the scene where fraternity president Mike Ryan is giving instructions to the other fraternity brothers on how to vote and behave during this process. At the exact scene where Mike Ryan says, 'Your absolute silence is required', in the background we see Steve and John Sears staring down each other in anger. A split second later just as Mike Ryan finishes that sentence, the camera shot now just shows Steve sitting straight forward, looking down at his lap slightly in a kind of sad, defeated state.
The Time Has Come Today - S4-E25
Factual error: The diary that Brenda finds has a Precious Moments figure on the cover. Wendy, the character who owned it, wrote it between January 1968 (an entry mentions her new year's resolution) and August 1969 (when she attended Woodstock), but the company didn't exist under that name until the late 1980s.
Vital Signs - S4-E30
Continuity mistake: Near the beginning of this episode Andrea is awakened at 3 A.M. by an alarm clock to take a pill to stop her preterm labor. Several times in the episode it is mentioned she must take the pill every 4 hours. Later the alarm goes off at 8 PM the same day and she says "time for the pill again that is not doing me any good". If the alarm went off at 3, 8pm doesn't fit the 4 hour timeframe.
Mr. Walsh Goes to Washington (2) - S4-E32
Audio problem: During the scene where David and Babyface are talking and Babyface asks David to fill in as one of the keyboardists for his carnival show, the camera shots going back and forth from both behind David and Babyface show them speaking, but it is very clear their words don't match their lip movements.
Continuity mistake: When Jesse takes Dylan's shot glass, he grabs it at the bottom, but in the next shot, he's holding it near the rim. (00:28:55)
Other mistake: There was an error regarding the captions on this episode. When "I'm Gonna Get You" was playing at the rave, the captions displayed the lyrics for "Every Day of the Week." Then when "Every Day of the Week" was playing, the captions displayed the lyrics for "I'm Gonna Get You."
Continuity mistake: When Steve is talking to his dad after he finished his case in court, one shot Steve's suit jacket is buttoned up. In the next second it is opened and all the buttons are down. (00:32:40)
Christmas Comes This Time Each Year - S5-E15
Visible crew/equipment: When Christine Petit opens the door and says "Hello Dylan" and Dylan says "Christine" the other agent walks out of the room and as he is closing the door a microphone is seen above Christine's head. (00:18:00)
Visible crew/equipment: Brandon and Dylan are in their hotel room and Brandon is talking to Kelly on the phone. Right after she says, "Are you sure you two aren't shackin' up with some biker babes?" it goes back to Brandon and you can see a boom mic above his head. It then continues until about when Dylan walks out of the bathroom.
Hazardous to Your Health - S5-E18
Continuity mistake: When Jonesy transfers Dylan's money out of the Cayman Island account, he is seen holding his hands around his neck. In the next shot he has his left arm down by his side and his right hand balled into a fist in front of his face. (00:32:45)
Lover's Leap - S6-E5
Visible crew/equipment: When Brandon is talking to Val in the kitchen, right after he says, "She had her moments," you can see a boom mic above Val's head.
Angels We Have Heard on High - S6-E15
Other mistake: In the scene at the Peach Pit where Rush tells Steve that he is his biological father, he shows Steve a copy of the birth certificate. Under adoptive parents, it lists Sanders, Rush and Sanders, Iris. Only Iris isn't Steve's adoptive mother, Samantha is. Iris is Dylan's mother who lives in Hawaii.
Continuity mistake: When Colin and Kelly celebrate his selling some of his artwork, the head in his glass of champagne disappears and then reappears.
Continuity mistake: When they are watching Colin's car chase at television, Colin is wearing an orange shirt. But Colin was wearing a grey shirt before the car chase started, and he is also wearing a grey shirt when he is caught.
Continuity mistake: Taz (lead singer of group Donna and David are producing a music video for) recognizes Kelly from her 'Seventeen' magazine cover and mentions it was in spring (May) 1994; however that was still the gang's freshman year in college (Season 4) and Kelly did not do the Seventeen shoot until season 5, and the magazine cover was out in the spring of 1995.
Continuity mistake: When Steve is talking to Valerie, after getting out of the shower, about Coming Home early to surprise Claire, you can see shaving cream on his ears. When the shot changes to a side view of him sitting on the bed, he no longer has the shaving cream on his ears. When the shot changes back to looking at him head on, the shaving cream is back on his ears. This goes on for the entire scene.
Continuity mistake: When Donna talks to David about their childhood, Donna's hand moves from stirring her drink to resting on her arm between shots. (00:04:15)
Continuity mistake: In this episode, a main story line revolves around Steve and Kelly's supposed first and only sexual encounter, at the beach club while they were in high school. Sorry, but the early episodes made it clear that they slept together many times while dating, and The First Time was in Steve's room while his mother was being interviewed downstairs.
Character mistake: When he arrives at his hotel room in Vegas, David is surprised that Ray is performing at one of the casinos. But at the beginning of the episode, Steve told Brandon that Ray was performing, which suggests going to see him was part of their plans. So either (1) Steve shouldn't have known Ray was performing there, or (2) David shouldn't have been so surprised.
We Interrupt This Program - S7-E18
Continuity mistake: When Rusty leaves the CUTV news room, he has his backpack slung over his shoulder. In the following shot, he picks the bag up off the table and slings it over his shoulder again. (00:16:25)
