Cesar Millan’s big week continues with the 100th episode of “The Dog Whisperer” (8 p.m., National Geographic). The celebrated dog trainer assembles many of his successful cases, including Wilshire the fire dog, Luna, Kane the Great Dane and the Pink Lady and her pink dog. Millan’s two-legged fan club appear as well, including celebrity guests Jada Pinkett Smith, Patti LaBelle, Virginia Madsen, Ed McMahon and Daisy Fuentes.

The rapid replay of Millan’s greatest hits and rescues remind us that he’s much more of a human trainer than a dog therapist. Entirely too many of his clients put their pets’ indulgence ahead of their family’s welfare. The recaps underscore Millan’s zest for launching into New Age aphorisms and other forms of dogged Oprah-speak. He utters the phrase “calm submissive state” so often that it begins to sound like a satellite campus of the University of California.

¢ On tonight’s “20/20” (9 p.m., ABC), Diane Sawyer interviews actor Alec Baldwin, the Emmy-nominated star of “30 Rock” who can’t seem to avoid controversy.

In a recent profile in The New Yorker, Baldwin appeared less than thrilled to be associated with a situation comedy and offered unsolicited and uncharitable comments about other NBC comedies, including “My Name is Earl” and “Scrubs.”

The character that emerges in the magazine piece is at once pompous and miserable, an awkward combination of working-class Irish Catholic pugnacity and pampered Hollywood entitlement. It’s hard not to groan when someone bemoans his descent from A-list movie stardom to “mere” TV celebrity.

At the same time, Baldwin’s bravado and self-loathing come across brilliantly in his arrogant and deeply neurotic “30 Rock” character Jack Donaghy. Who says geniuses don’t suffer for their art?

Baldwin can also be seen tonight in the 2001 war epic “Pearl Harbor” (7 p.m., AMC).

Cult choice

Exploitation movie king William Castle directed the 1960 shocker “13 Ghosts” (1:15 a.m. Saturday, TCM), originally released with special glasses that allowed viewers to “see” the ghosts. The 1959 thriller “The Tingler” (2:45 a.m.) was released in theaters outfitted with electric buzzers in every seat to scare the pants off its audience.
