So if you do your query for '/guid/9202a8c04000641f80000000002eb15e',  
which is the movie 'Hard Eight', there's no evidence of the Character  
property of Film Performance in the MQL response because while there  
are several CVT instances with the Actor property filled-in, none have  
the Character property set.

Interestingly enough, though, in the course of looking for an example  
I found that freebase.com seems to have the same issue (no Character  
column):
