International box office returns for 2005 show that Harry Potter and the Goblet of Fire was the number one movie of the year, beating Revenge of the Sith by $67 million (£38 million).
These figures excluded North America where Revenge of the Sith beat Goblet of Fire by nearly $103 million, but one should note that Goblet was released in November while Revenge of the Sith opened during the summer months so it had a longer shelf-life in theaters, especially domestically where the movie did extremely well.
There is also a poll on the BBC website asking which movie, Revenge of the Sith or Goblet of Fire you preferred. Currently Goblet is leading 52.47% to Revenge's 47.53%.
To date Goblet of Fire has accumulated $811.9 million dollars in ticket sales.
