If you're looking for the season finale of "Archer," it'll be under the sea. With Jon Hamm!
According to the AV Club piece, the FX series has been pulling in some of the highest ratings on cable for that advertiser-coveted demographic of men age 18-34. That--coupled with the fact that it's one of the most smartly-written comedies on TV right now--has secured it a slot in what I presume will be the 2014 season.
Plus, the April 4 episode will guest star "Mad Men" star Jon Hamm in a "Sealab 2021" riff for the two-part finale, as “Captain Murphy, the possibly deranged commander of an undersea laboratory.” "Archer" creator Adam Reed co-created "Sealab 2021" as part of the first wave of Adult Swim programming back in 2000. Hopefully, this means we might see a "Frisky Dingo"/"Archer" crossover at some point in our future? "Xtacles vs. Archer?"
Hamm will be standing in for actor Harry Goz, who played Captain Murphy in the series until he passed away in 2003 at the age of 71.
