Sean Bean not right for Boromir

[Carlas]

By the by, where exactly does it say that Borrums has a different build than Ary?

I think I remember it being mentionned sometime in the chapter The Ring Goes South, but I'm not too sure because I haven't read it in awhile.

But now to the topic:
Sean Bean was a great Boromir, and I think that PJ realized that the acting was more important than the look. Though I'm not saying he would have picked someone like 6 feet tall, but being broader than Aragorn does not seem that important, except maybe to some die-hard book fans.
