The trailer makes it look a bit like Poirot on acid. So over the top but beautifully styled and funny with it.
It reminds me of an old black and white film made in 1932, Grand Hotel. I remember seeing this when I was a child, not in the 30s I hasten to add I'm not that ancient.
I suspect the Anderson film will have a similar format and plot with an incredibly different look and feel. Can't wait.
