Good morning, world! Go to hell.

“Morning Glory” is a funny entertainment to begin with, and then Rachel McAdams transforms it. And Harrison Ford transforms himself. She plays as lovable a lead as anyone since Amy Adams in “Junebug,” and he bestirs himself from his frequent morosity and creates with gusto a TV newsman who is described as a great man, but the third worst person of all time. Diane Keaton is pitch-perfect a Colleen Peck, a morning TV host who can, and must, smile through everything.

Comedies open every week. This is the kind I like best. It grows from human nature and is about how people do their jobs and live their lives. It is wisely not about a May-October romance between McAdams and Ford. It's more about their love for their work. It isn't deep, and it doesn't approach “Broadcast News” in its examination of the TV producer mentality, but it's the kind of sitcom you can get happily carried along with.

McAdams plays Becky Fuller, a little Energizer Bunny of a morning TV producer, who gets fired from her thankless job in New Jersey, and then has the good, or bad, luck to be hired to produce a last-place network morning show. Her boss is the dubious Jerry Barnes (Jeff Goldblum), who possibly views himself as the hiring agent for the Titanic. Becky plunges with zeal into a show that is not merely stuck in its tracks, but congealed. At the first staff meeting, Becky comes across as a featherbrained lightweight until, in a nice burst of dialogue, she reveals she has heard everything, had strong opinions about it and fires Peck''s current co-anchor.

Fuller's assignment: Turn the show around. The network has one of her heroes handing around, working off the end of his contract. This is Mike Pomeroy (Ford), who detests what has happened to network news. Becky discovers how much time he has left on his contract and forces him into taking her show's co-anchor gig. This involves precisely the kind of news he hates, and he'll have to do some of it, even though Colleen Peck's game enough to kiss a frog for more ...Good morning, world! Go to hell
