I saw IT last week, only it was actually Ça, considering I saw it in a cinema in Liège. English-language films are generally dubbed here, but as it was a somewhat arty cinema, they were proud to offer the VO (version originale) with French and Dutch subtitles. Having two sets of subtitles taking up space on the screen is quite distracting, but it’s an interesting opportunity to compare English, French, and Dutch at the same time.
Watching a film with subtitles in a language you know is always a little odd, as they never translate things exactly, largely because such a thing is basically impossible. Even so, there are always one or two choices the subtitler makes which boggle the mind. I don’t recall anything like that in this case, but there was one necessary difference in translation that intrigued me.
