I'll leave it to one of the ladies to give us judgment on Gary Cooper's charm.
For me, this is Ingrid Bergman at her absolute best. Shot just after Casablanca, the screenplay and Sam Wood's common sense choose to focus on Ingrid in every scene but the brief, although well done, train wreck and brawl.
She is radiant, sly, coquettish, warm, reactive, piercing, soft, hard. Most of all, she is desirable. A woman for all time, for all women.
And she is strong. Melting for a brief second, gathering her resolve and forging ahead with her plans and schemes.
The Edna Ferber novel has enough truth to provide a reasonable story line for Ingrid to carry along single handedly. Cooper and Jerry Austin as Cupidon are excellent. Florence Bates gets too little time, too late as a matron with claws.
And French, yes, bless them, they allowed Ingrid to speak French, which she did so beautifully.
The current 6.2 Yahoo rating is laughable. "Saratoga Trunk" may not be a "Casablanca" or "Notorious" but it is far better than this lowly rating. See for yourself.
