I downloaded a 1080p movie but it doesn't say it's 1080p?

I recently downloaded Man of Steel, the 1080p version of it. The file was 5.34 GB and was promised to be 1080p. However, when I access it from the windows file explorer (Windows 10), it says that the frame width is only 640 pixels and the frame height is only 266. I expect it to be around 1920 and roughly 900 respectively. Attached is a screenshot:

Why does it say 266x640 when it should be much higher? Does this mean that the file I downloaded gave out false information from itunes?
