Audio problem: Near the start of the show, Frasier is in the booth at KACL, and has told Roz off and is glaring at her through the glass. As the shot shows her face, however, we can see the reflection of Frasier in the glass - he is smiling and his lips are moving as though he is talking. However, there is no audio to match his speech.
Continuity mistake: Martin and Daphne are laughing at Eddie who has taken a pill to calm him down - in one shot he has a paw up in the air, but in the next shot both paws are pointing sideways. The shot changes again, and Eddie is back in the first position. He had to time to change naturally.
Continuity mistake: Eddie is sitting in Martin's chair while Daphne feeds him pate from a plate on Marty's table. At the same time she is scratching his ears. The shot changes, and without enough time for this to have happened naturally, Eddie is lying on the chair and Daphne has the plate in her hand.
Visible crew/equipment: Halfway through the episode, the new station manager says she has to fire someone. If you look at the top of the screen by the white box on the wall, you can see the boom mike.
Visible crew/equipment: A boom mic is briefly visible when Frasier is talking with Kate in the hall. (00:11:09)
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.
