The top movies report uses a weighted rank calculated as follows:

 weighted rank (WR) = (v ÷ (v+m)) × R + (m ÷ (v+m)) × C

 where:
  R = average for the movie (mean) = (Rating)
  v = number of votes for the movie = (votes)
  m = minimum votes required to be listed in the top 50
      (currently 200)
  C = the mean vote across the whole report
      (currently 6.9)
