M.G.M. has again grabbed a hold of Hollywood's sure-fire formula for money-making movies. It has tossed together a bunch of old song favorites, a couple of snappy new tunes, some lavish dance spectacles, a hoofer who can hoof, and a singer who can sing. The result is "Lady Be Good," a sizzling pot-pourri of entertainment which tops anything in its line that has been turned out since Ann Sheridan became the sweetheart of the Harvard Lampoon.

Ann Sothern, although she still looks like Maisic, warbles with plenty of enthusiasm and not a little artistry; aided by a cleverly guided camera, she does a top-notch job with "The Last Time I Saw Paris," and in the rest of her numbers manages to do more than her share of scene-stealing. Eleanor Powell, away from the screen for too long, taps and jigs effectively, although she isn't given much to do. These two, aided considerably by some fellows named Kern, Gershwin, and Hammerstein, contribute a hearty portion of sparkling entertainment. The plot--since movies, it seems, must have plots--is bad enough to be annoying, but unobnoxious enough to be ignored. Robert Young struggles to keep it going; the fact that he doesn't succeed doesn't bother anyone, least of all the audience.

"The Lone Wolf Takes A Chance" rounds out the bill, in a convincing argument against double feature movies.
