Roz's Turn - S4-E17
Continuity mistake: When Frasier and Roz are in his kitchen talking about audition tapes, sometimes he is holding a glass of sherry and sometimes he is not; it is not a case of him putting it down, as the scene goes to quickly for that. During the same scene, Roz's beer switches hands, and there was no time for that either.
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.
