It’s alive!

Is it Halloween already? Because they’re raising former TV stars from the dead this week:

“Person of Interest” (Thursday, 9 p.m., CBS) Margo Martindale has been laying low since snagging that Guest Star Emmy for her wonderfully sadistic mother on “Justified.” This week she guest stars as a woman with connections to hacker Root (Amy Acker), who still has Finch (Michael Emerson) after kidnapping him in last season’s finale.

“Parks and Recreation” (Thursday, 9:30 p.m., NBC) Lucy Lawless has had been getting steady work on Starz’s “Spartacus” as the conniving widow Lucretia. But for those who still fondly remember her days as Xena, Warrior Princess, you can tune in to this quirky comedy where she pops up as a local mom whom Ron (Nick Offerman) is sent to help.

Considering Ron’s affection for strong women, hunting and all things meat, the Pawnee Parks director will undoubtedly fall for the Amazon warrior.

“CSI: NY” (Friday, 8 p.m., CBS) Rob Morrow, who will always be Joel from “Northern Exposure” but whose last memorable effort came in “Numb3rs,” shows up in the two-parter premiere as a disheveled serial arsonist who’s been recently paroled.

“Hawaii Five-0” (Monday, 10 p.m., CBS) At least they didn’t wait another 30 years to ask back Ed Asner. He first reappeared last season as art smuggler August March in the role he created for the original 1970s series. This week, the 82-year-old visits the series that doesn’t realize it should be hip enough not to need octogenarian guest stars when the team investigates a deadly art heist. Asner hasn’t reached the comeback status.
