It has been stated over at
IMDB that
Harry Potter and the Goblet of Fire, the fourth film in the series, is now in
post-production.
Post-production is what happens when filming is near or has reached completion. During this time the effects are added and the film is edited.
This would fit with
earlier reports that
stated that filming for '
Goblet of Fire' would
finish sometime between February and April, of this year.
However, as this is IMDB saying this and not WB, we should still be wary.
