I don’t know about you, but I’m very much in the mood these days for a sweet-natured, funny and more than a little whackadoo movie about a small and very polite bear named Paddington who wears a blue overcoat and carries an umbrella.

“Paddington in Peru,” the third film in the franchise that’s rapidly becoming my favorite cinematic universe, doesn’t quite reach the levels of lovable lunacy reached by “Paddington 2” (the movie for which Hugh Grant, as a hilariously self-absorbed actor/crook, should have won an Oscar or three), but it’s a joy all the same.

Dear Hollywood: Please put well-spoken bears in all of your movies. Thank you.

“Paddington in Peru” begins with Paddington (voiced charmingly by Ben Whishaw) in familiar territory. The bear, named for the London rail station in which he was found, lives happily with the Brown family — father Henry (Hugh Bonneville), mother Mary (Emily Mortimer, taking over the role from Sally Hawkins) and older teen children Judy (Madeleine Harris) and Jonathan (Samuel Joslin) — but is alarmed when a letter arrives from South America. His beloved Aunt Lucy, who lives in a Home for Retired Bears in Peru, is rather poorly; might Paddington come for a visit? Of course he can, and all of the Browns, along with housekeeper Mrs. Bird (Julie Walters) decide to come along, for a family adventure.

Surely I need not say that many things go awry on this trip (not least of which is Paddington’s harrowing encounter with a hammock), but that everything turns out splendidly in the end?

And that Olivia Colman’s delightfully unhinged performance as a perpetually smiling, guitar-wielding nun steals the movie? (Colman’s Reverend Mother always seems ever-so-slightly confused, but determined to beam her way through the problem).

And that the movie is full of tiny moments of delight, such as Jim Broadbent saying “good afternoon” to a shrub (everyone in this movie is enchantingly polite) and teen-boy deodorant spray used as a force for good?

And that, honestly, I got a little teary over the reunion of two CGI bears, and the very idea of a movie filled with love for immigrants and found family? Stick around for a treat in the end credits, and cross your fingers for “Paddington 4”; we all deserve no less.
