It's a useful trailer. It tells the skeptics of Wes Anderson not to get their hopes up too high. The theme of a disjointed family coming together looks the same as Life Aquatic and Royal. This film also looks to have exactly the same filmmaking scheme as those films as well. Hopefully the finished product shows some
growth from Anderson.
On the plus side (not that Life Aquatic is bad - just don't want it again), "featuring music from the films of Satyajit Ray and Merchant Ivory" sounds like a promisingly weird and interesting twist.
Weird, yes, but the question is: will there be a point? I'm afraid Anderson is doing this for the tie in of both a cultural and filmic reference. No bother that both references have little do with each other or even Anderson himself, but hopefully it has something to do with the story besides the generic. It will be a tough sell.
