So, for starters, here's a look at the guest acting nominations for comedy.
GUEST ACTOR IN A COMEDY SERIES
Mike O'Malley, Glee
Neil Patrick Harris, Glee
Fred Willard, Modern Family
Eli Wallach, Nurse Jackie
Jon Hamm, 30 Rock
Will Arnett, 30 Rock
There's several really good nominations here. O'Malley had some great scenes in Glee, and its nice to see the longtime bit-player get some recognition, but a lot of his scenes are more serious than funny, which they may hold against him. The same goes for Wallach, who has great scenes with Edie Falco but they're more dramatic. Hamm, though great, is the puzzling nomination, since he had less than two minutes of screentime; he's probably the least-deserving for this category. Arnett had a great guest spot as well, but it was more or less the same performance that he's done better on the show. I think this one comes down to Willard and Harris: Willard gives a great performance as Phil Dunphy's father, playing the emotional disconnect between them excellently, but I think this one is going to go to Harris, who had the most complete arc and diverse performance (he sings! he dances! he acts!) as Bryan Ryan on Glee.
GUEST ACTRESS IN A COMEDY SERIES
Christine Baranski, The Big Bang Theory
Kathryn Joosten, Desperate Housewives
Kristen Chenowith, Glee
Tina Fey, Saturday Night Live
Betty White, Saturday Night Live
Elaine Stritch, 30 Rock
Jane Lynch, Two and a Half Men
There's certainly an interesting mix of nominations here this year. Joosten is a favorite for her role in Desperate Housewives, but maybe they've honored her enough by now? Lynch is mostly riding the Glee wave and earned another nomination here, which she most likely will not win. Stritch did well on 30 Rock, but like a lot of that show's guest nominations, its more of the same. Fey's hosting gig at SNL was good, but it was not a hilarious high for the show or the actress. And Baranski seems like more of a lock for the Supporting Actress in a Drama Emmy than this one. So rely on White to coast on her (somewhat overrated) popularity to win this one.
