Mickey Rooney is still Mickey-Rooney, but his clowning and wise antics in "Andy Hardy's Private Secretary" are still packing the house regardless of the size of the Cambridge delegation. Few class presidents ever had as much trouble graduating from high school as activities man Rooney has when an English exam throws him. But helped in a cram session by the two talented lads and sweetheart Judy Garland as Polly, he pulls the coals out of the fire, and now Andy Hardy fans are impatiently awaiting his choice of a college.

Judge Hardy's advice to adolescents continues, with a couple of plugs for the good old U. S. A. and the good-neighbor policy thrown in, but a new note is sounded by singer Kathryn Grayson as Andy's "secretary." She draws considerable applause with her pleasant soprano voice, but has yet to give her operatic and popular renditions some everyday pep.

On the same billing is "Ellery Queen, Master Detective." Hollywood didn't waste much time on it, and there is no reason why anyone else should.
