Continuity mistake: Frasier and Niles are in the kitchen at the cabin. Niles picks up his mug to take a sip, but in the next shot his mug is still on the table.
Continuity mistake: When Frasier and Marty are talking about going to Ronee's cabin, Ronee is sitting on the right side of the couch with nothing behind her. In the next shot, she gets up and we can see a light brown overcoat. This coat disappears again in the next shot, as Frasier answers the door and Niles comes in, carrying the very same overcoat which he places on the right side of the couch, where Ronee had been sitting.
Continuity mistake: Nanny G and Frasier are in the kitchen of his apartment and there is a tray with three empty wine glasses. Nanette takes one and pours herself some wine; a few seconds later Frasier grabs the tray and goes into the living room, but now he has four empty glasses on the tray when there should have only been two. At no time did he add glasses to the tray.
Continuity mistake: Daphne comes into the Cafe and asks Marty, "Where have you been?" and her purse is on her right shoulder. In the next shot her purse is in her hand, but not enough time had passed for this to happen naturally.
Continuity mistake: At the very start of the show, Frasier is pretending to conduct an orchestra with a wooden spoon. Marty says "Boo," and we see the spoon in his right hand. Then Ronee says, "He does scream like a woman," and suddenly the spoon changes to his left hand and is turned the other way. Frasier had no time to change it.
Continuity mistake: At the hospital the nurse comes over to talk to Frasier about his father - her paper on her clipboard is flipped over the back of it and her hand is holding the side of it. A couple of shots later, with no opportunity to change positions, the paper is no longer flipped over and her hand is lying on top of the clipboard.
Boo! (a.k.a. I'm With Her) - S11-E16
Continuity mistake: Marty is home from the hospital and there is a basket of flowers on the coffee table. The basket moves several inches to the left while Niles goes to the door to let Ronee in.
Boo! (a.k.a. I'm With Her) - S11-E16
Continuity mistake: In the first scene after Niles walks in and takes his coat off. The left-hand side of his shirt collar alternates between tucked underneath his jacket and sitting outside it.
Match Game - S11-E18
Continuity mistake: While Niles, Daphne and Marty are watching the video of Cindy's labour, the bag of Marty's cookies change position a few times - from being in his chair to being on his little table, and back again.
Match Game - S11-E18
Continuity mistake: Frasier and Roz are in the Cafe talking about the dating service - Roz is holding her mug by its side in her right hand - it switches from her holding it by the side to holding it by the handle and from one hand to the other several times during the scene.
Match Game - S11-E18
Revealing mistake: 4 minutes into the show, Frasier gets off the elevator and goes to an office door with keys to open it, he tries the keys and they don't work. He realizes he missed his floor. A woman opens the door and they start talking about a dating service which he says he doesn't need, and he pushes the elevator down button, which lights up. The doors open and a man gets off. It's going up, which he finds out from an ex-girlfriend on the elevator. The down button light goes out before he gets on to go up with her. The light should only have gone off on the way back down.
Match Game - S11-E18
Continuity mistake: The scene where Charlotte comes to Frasier in the restaurant to tell Frasier his date has cancelled is poorly edited between shots. Watch the folder once she has pulled it out: in almost every shot, the side facing the camera changes, and when Charlotte gets up, it disappears completely.
Continuity mistake: In the opening scene, Ronee and Frasier are talking at his table about her mother. Frasier asks, "She doesn't approve of premarital sex?" and his arm is folded in front of him. In the next shot, his elbow is on the table and his hand up in the air. Later on in the scene, Ronee's mother shows up at the door and we see Marty lunge to the right to grab his cane. A couple of seconds later the shot goes back to him and we see him lunge to the right for his cane again.
Continuity mistake: Frasier and Marty are sitting in their living room talking about Frasier's problems with women. Marty has his fork poised above a plate with a slice of cake on it. The next shot shows the fork on the plate, next to the cake. Marty would not have had time to put the fork down in the split-second in between.
Continuity mistake: When Niles and Frasier are in the cafe discussing how many patients have fallen in love with them, Frasier claims 13. But in the episode "The Maris Counsellor," he states no patient has ever fallen in love with him. OK, time has passed, but he's done hardly any private practice since then, and any he did do was shown anyway.
And Frasier Makes Three - S11-E20
Continuity mistake: Frasier picks up a couple of paper bags full of stuff for a picnic he is going on with Charlotte and her boyfriend - there is a fabric string/tie hanging out of one of the bags as he heads for the door but when he gets there, it has disappeared.
And Frasier Makes Three - S11-E20
Audio problem: There are two audio problems in this episode, both in the same scene. Frasier is in his apt. talking to Niles, Daphne, and Martin. After Marty says, "Wow, really?", we hear a couple of garbled words while Niles' lips move. Then as Frasier heads to the door, Daphne asks, "How'd he hurt himself anyway?" While she is saying this, we can hear a phone ringing faintly. It is not coming from on stage, no one moves to answer a phone, and it has no part of the plot.
Revealing mistake: During the scene where Frasier is dropping Charlotte off at the train station (the first time) you can see the background behind him shows that the car they are in is turning left. Yet we can see his hands on the top of the steering wheel and during this time he never turns the steering wheel.
Other mistake: This is for the episode "Crock Tales" (the 22nd of the season). Almost all the flashback sequences are wrong in time. The one from 2003 has Niles and Daphne coming back from their honeymoon but they married in 2002. Although not ever couple take their honeymoon directly after they've married, the wedding episode "Ring Cycle" mentions them going on their honeymoon.
Answer: It equals the record of James Arness of "Gunsmoke" for the actor who's played the same part on TV NOT in a soap opera. If you include soaps there are two main contenders - William Roache, who's been playing Ken Barlow in "Coronation Street" in the UK since 1960. Don Hastings has been playing Robert Hughes in US soap "As the World Turns" since 1960 as well.
