Impossible not to like both, however, if stranded on a desert isle...
OK, for me it is impossible not to thoroughly enjoy both High Society as well as The Philadelphia Story...
...having said that, however, were I marooned on a desert isle and could only take one or the other, I would have to pick The Philadelphia Story. I remember actually being a little shocked (although I KNEW that HS was a musical) when the first song suddenly broke out. And although it's terribly unfair, I know, to compare the casts, Katharine Hepburn will ALWAYS be Tracy Lord, just as much as Cary Grant will be "good old Dex".
So I ask - had you to choose to take along to re-watch for the remainder of your natural life (for I am certain that BOTH versions will be available for viewing at any time in Heaven!) which would you choose?
