actually those we're characters pulled from other books which surround the time of the journey also written by JRR Tolkien referred to as Tolkien's legendarium
, which they integrated into the movies to elaborate on the story line as well as add to the time (how else we're they going to get three movies out of that book). I was confused as well, until my nerd of a partner explained to me all the added characters as they appeared on screen.
As for myself, my biggest pet peeve is when movies choose actors which have no resemblance to the character in mind or when a character changes a little too much over time (see hermione's hair from the first two films vs the others), or when big details are left out or just not talked about - such as the scene in Choked where the fellows are at the bar drinking milk, and is then never explained, which may have been just something put in for fans of the book and gone unnoticed by other viewers, but for those who did not read the book and realized they would have been fairly confused.
