Can you check your xbmc.log - it's xbmc that is failing to download the artwork.
You may need to enable debug. For some reason XBMC can't access your artwork, sometimes this can be due to a temporary website issue, or worst case the remote files may permanently no longer be available (one of the perennial problems when using remotely hosted artwork). However in this case the site and artwork appears to be available, so maybe your XBMC client is having network issues? Hopefully there will be more details in xbmc.log.
As for "Son of Batman", if it's not being returned it's either not in the cache, or it's there with a different name. Look at the movie details with "jd movies "son of batman"" to get an idea of what artwork files are being referenced and thus likely to be in the cache (assuming they've been cached).
