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.
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.
