wetHotThe original “Wet Hot American Summer” about a camp’s last day in 1981, became a cult classic since its 2001 release, in part because of its cast that included Amy Poehler, Bradley Cooper, Elizabeth Banks, David Hyde Pierce, Michael Ian Black, Christopher Meloni, Paul Rudd, Janeane Garofalo.

It was weird last year when most of them showed up, 14 years later, for the Netflix series that was set on the start of that camp year, instead of the film’s final day.

Now, with “Wet Hot American Summer: 10 Years Later” (Netflix, streaming) they’ve found a more agreeable premise that accounts for the aging cast, set in 1991. Like the others, it’s written by David Wain and Micael Showalter and directed by Wain, and includes a lot of the original cast, including Molly Shannon, Rudd, Poehler, Zak Orth, Marguerite Moreau, Meloni, Black, Garofalo and Pierce but also Kristen Wiig, Lake Bell, Jason Schwartzman, Alyssa Milano, Mark Feuerstein, Marlo Thomas, Dax Shepard, Melanie Lynskey and a bunch of other people. You will hardly miss Bradley Cooper.

Another fun new online show today, “Comrade Detective” (Amazon, streaming) purports to be unearthing a 1980s Romanian crime series, when they’re actually creating in Romania and dubbing the goofy action, with voices provided by Channing Tatum and Joseph Gordon-Levitt and guests Nick Offerman, Jenny Slate, Chloe Savigny and Jason Mantzoukas.
