While they are sitting in the van after Chip's and Steven's trip to the satellite dish, Chip gives a very corny, contrived smile. In the next shot, Chip is not smiling.
Steven drops the prison phone twice.
The telephone handset suddenly appears in Chip's hand as he talks to Steven in jail.
At Steven's parents' house, Steven calls Chip a "bastard" and
covers his mouth in shock at what he said. In the next shot, his hand is no longer over his mouth.
During the jousting scene when Steven hits Chip with the lance, Chip's lance and shield fly the opposite way Chip does, but when Chip hits the ground they are right next to him.
There is no "switch" than turns on and off the cable reception, as depicted in the hallway of Steven's apartment. For the cable to have gone out like that, the cable would to have been disconnected completely. The switch that "Chip" turns on and says "All set!" is most like the switch for the 4th floor hallway lights at the apartment building where Steven lived.
Steven and Robin have just started to watch Sleepless in Seattle (1993) having missed only the first few minutes, but the scene shown when the cable comes back on is from the middle of the movie.
After Steven gives Chip the tape to help him with his lisp, and the two are mimicking guitar riffs from the song playing on the Karaoke machine at the time, "American Woman" by the Guess Who, and Chip comes out into the living room, the closed caption has him saying "already bopping'" which is completely wrong. What Chip said was "Randy Bachman!" referring to the lead guitarist in the band, Guess Who.
The satellite dish has no transmitting or receiving device on the apex. Only another mini-dish.
When Steven and Chip (Cable Guy) go to Medieval Times for a night out, they enter the "arena" and engage in role-playing combat after dinner. Medieval Times does not allow ANYONE in that area except for the professionals who portray the various "combatants" and the staff that maintains the area. In a humorous turn of events, many fans of the movie sought to go to Medieval Times if there was one near where they lived, and explained they wanted to go out and battle like the film's characters had. Each branch told them that for insurance liability and sheer risk reasons, this wasn't possible.
"The odds that Steven would have been in jail (the prison scene) for "receiving stolen property" are slim to none, and after an interview Steven would have likely been cited at the police station and given a court date. Some states have a separate but similar charge called "possessing stolen property" or "possession of stolen property." The distinguishing factor here is when the accused learned the goods were stolen. If he knew at the time he acquired the property, then it is receipt of stolen property. It is possession of stolen property if he only learned the property was stolen after he obtained it. All Steven had to do was tell the police who Chip Douglas really was, and Steven would have been sent home and it would have been The Cable Guy who would have been arrested."
... but the Police Officers and Guards seen in these scenes are all "Preferred Customers" and they clearly went outside the law to lock up Steven at the request of Chip. Since this is still a comedy film, the suspension of disbelief is held when it is acknowledged at least twice in these scenes that Chip is manipulating the authorities with his connections via long-time cable hook-ups; and we'd seen the arresting cop at the karaoke party earlier in the film, too.
The angle of the video of Steven and Robin on the couch is different than the camera angle that chip placed in Steven's apartment; as it was positioned, only the bottom half of the couch would have been in the field of view.
During the basketball game at the gym, after Chip shatters the backboard, he falls down into the glass on the floor. However you can clearly see an outline within the shattered glass, where he should land.
In the bathroom scene when Chip Douglas is beating up Ray (Owen Wilson) he throws him onto the hand dryer while it's on and makes him suck on it showing his face blowing up. When Ray takes his mouth off there was clearly no air coming out to begin with because his hair is standing still while he is standing in front of it.
After Chip installs Steven's cable and moves his furniture, no cable can be seen, either going into the TV set or coming out from the wall.
The closed captions read in the middle, when Chip has his Karoake party, "Already Boppin'!" because the interpreter misread what Chip actually said, "Randy Bachmann" which was his referring to the Guess Who's song on the Karoake Machine, "American Woman" which was a group from Canada.
The answering machine owned by Steven is a digital machine. It does not use a tape to record messages. Therefore, when Steven hits the "skip" button, you should not hear the tape fast forwarding, because there isn't one. Also, you should not hear the tape clicking on a new message.
The visuals in the clip from the Ren & Stimpy episode "My Shiny Friend" are out of sync with the audio.
About half way through the movie, a spider crawls up the camera lens.
The satellite dish Chip falls into is pointing straight up. Satellite dishes track satellites in geosynchronous orbit, which must orbit at the equator. For the satellite dish to be pointing straight up, it must be on the equator.
When Chip slam dunks a basketball, the backboard shatters. Since the 1970s, when dunking became popular, backboards have been built with breakaway rims to make sure this doesn't happen.
The Hell's Angels stabbed Meredith Hunter (after he pulled and fired a .22 revolver) while The Rolling Stones were on stage, not Jefferson Airplane. They were performing "Under My Thumb".
At the karaoke party, Chip sings "Somebody to Love" by Jefferson Airplane, which he says was featured in Gimme Shelter (1970), the documentary about The Rolling Stones concert at Altamont. Jefferson Airplane plays "The Other Side of This Life" in the movie, not "Somebody to Love."
Steven and Rick (Steven's "Rock" friend) act as if computers and search engines did not exist, having to resort to a research department to find "Chip Douglas" which could have easily been done with the search engines that existed at the time the movie was made: Lycos (1994), Alta Vista (1995), Excite (1993), Ask Jeeves (Ask), Infoseek (1994), Inktomi (1996), WebCrawler (1994).
Chip tells Steven "the arrangement of your furniture was causing some noisy pix and hum-bars in your reception," which is complete nonsense. Cable TV is a coax going directly into the TV itself and doesn't have "reception" of any kind, not to mention the arrangement of furniture has nothing to do with what appears on the TV screen.
There is no need for Steven and Chip to crawl under the gate at the dish site. They could just walk around it.
