Box Office Mojo
I usually got to BOM to see how a film is doing but there is virtually nothing there for this one. I've seen this a few times and wondering if it means (1) It's done poorly, or (2) not been released in the USA, or (3) too small to bother with, (4) any other reason.
Also, whilst we're on the subject of BOM I think the latest update is to be regretted - seems to be less info available for the casual visitor - maybe there is another & better site out there?
... (Edit)
To answer my own question - It's an Amazon production - I'm going to assume there is a very small cinema release after which it's small screen only. Which is a pity because it deserves the big screen.
