FWIW, as of this past weekend, The Muppets
has passed The Muppet Movie
to become the top-grossing Muppet movie
ever, in North America.
That's before adjusting for inflation, of course. The $65.8 million the new film has earned so far is currently good enough to make it the #44 film of the year, whereas The Muppet Movie
was easily in the top eight of 1979
(the site linked there gives a slightly different cume for the film than Box Office Mojo does, and ranks The Muppet Movie
way up at #4) -- and even The Great Muppet Caper
was #21 in 1981
FWIW, John Nolte
@ Big Hollywood says the film's disappointing box-office performance is not due to liberal content within the movie itself, per se, but due to all the attention that the media drew to that one Fox report. Parents, Nolte opines, were not avoiding the movie so much as "avoiding the controversy". For whatever that's worth.
