The least good of three films TCM showed last month to highlight the career of Arlene Dahl, a lovely actress with the emotional range of a reticent banana slug. Wonder who TCM will see fit to so honor in the not too distant future? Chris Noel? Arthur Hunnicutt? Lee Bowman? Natalie Trundy? The network that doubles down on Kay Francis as star of the month is obviously capable of great surprises.
