Continuity mistake: During the show, Daphne and Martin are having breakfast while talking to Frasier. Daphne removes her blue napkin from her lap at one point,and puts it on the table; a short time later we see her remove it from her lap again.
Continuity mistake: Roz is talking to Frasier, Gil, and Bulldog at KACL and has her hands in front of her, with her mug in her left hand. In the next shot, as she says "everyone at her last station was scared to death of her", her mug is in her hand tucked up under her arm - with no time for her to change positions naturally.
Continuity mistake: Kate is arranging things in her office and has placed a black and white box on her desk. As she is telling Frasier how she wants him to spice up his show, the box changes position by about 45 degrees although no one touches it.
Continuity mistake: Frasier has left his mug on the table to goes to console Father Mike who has just come out of Kate's office. The next couple of shots of the table show the mug in different positions.
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.
