The Muppets are back in a new show called The Muppets, not to be confused with their 2011 film, The Muppets. Seriously, Disney, have some pity on Wikipedia disambiguation pages.
News that The Muppets was being greenlit for series hit last week, and the pilot for the show was reportedly filmed almost exactly one month ago, so this trailer presumably comes straight from the footage that convinced execs that the series deserved a go. The mastermind behind the revival of the Muppets on television is Bill Prady, more famous now for co-creating The Big Bang Theory than beginning his career working with Jim Henson on Muppet media.
The trailer exhibits a certain fearlessness about what might constitute "all-ages media" that may come a shock to folks who haven't watched the classic Muppet movies in a while, or may have forgotten the strange topical asides and other fly-above-small-heads gags that populated The Muppet Show. After all, the concept of The Muppet Show was being pitched while Henson and associates were working on puppet sketches for Saturday Night Live.
