Oh Boro...you are such a fan girl.....
I have to say that although Bean was fine as Boromir taken in isolation, I thought it jarred that he kept his regional accent when the Australian actors chosen (and well chosen physically to be plausible) as his father and brother adopted "oxford english" accents.
I have no problem with regional accents per se - it was the inconsistency.
Bean can do Irish when the part demands and seeing as the majority of the cast weren't British but managed to do the accent pretty well, I don't see why he was allowed to get away with making Boromir sound different from his kin and country men. Dom Monaghan and Billy Boyd had hints of accents though I felt that was more acceptable since they are from different parts of the Shire. I know he kept his accent to play Macbeth (which is fine by me.. I don't think non-scots ever try a Scottish accent on that) but it did causee comment in some quarters. As I say it was the difference rather than the accent itself that bothered me....
But this is off topic .....but then since my previous post failed miserably to get the thread away from Boromir...
