Whether it is actually "record-breaking crowds" that bring about these periodical hold-over weeks, or whether there is something mysterious going on behind the scenes, is a question that has always intrigued us. Strange it is that the hold-over bug seems so frequently to strike several theatres at once; it is as if some deep, dark conspiracy were being hatched, either in Boston or else further West. On the other hand, the Boston palaces are notoriously jealous of their prestige,--as concerned with public relations as a Freshman on the Dean's List; perhaps the whole thing is a coincidence. At any rate, it is worth noting that of the three hold-overs in Boston currently running, only one is at a theatre incurably addicted to the practice. "Grand Illusion" at the Fine Arts is finishing its fifth, and 'its said final week; Jesse James, the rootin' tootin' gunman in technicolor, is shooting his way through a second week at the Met; and "Gunga Din," replete with a tribe of murderous Indian natives, is still at Keith's. All three, and especially "grand Illusion," are worth seeing; likewise the new Joan (Hedy Lamarr) Bennett, coming to Loew's in "Trade Winds"--of which this column will have more to say tomorrow. Finally, the latest reports indicate that the University has successfully weathered the Chicago fire and is coming forth today with Bing Crosby in "Paris Honeymoon." Concerning, of course, neither Paris nor a honeymoon, it is nevertheless in the approved Crosby manner--casual, sophisticated, sentimental, jocular.
