Question about characters
I just finished reading the book and liked it very much (despite somewhat contrived, "Hollywood" ending). It's not a masterpiece but still very powerful, poignant work of fiction and excellent material for ecranisation (Jim Sheridan is perfect director for this story). As much as I love Jessica Chastain I think she is a little old to play Roseanne - especially at the beginning. On the other hand Rooney Mara is 30 but looks younger so in my opinion it was good decision to cast her for the role after Chastain drooped out. And of course - the great Vanessa Redgrave. This role is tailor-made for her.
Reading IMDb cast I noticed that some characters from the book (Tom McNulty, Roseanne's father and mother, John Lavelle and John Kane) aren't listed which is strange because they are very important for the story. Very possible that some characters were omitted from the movie or just they don't have the same names. Maybe Tom and Jack are merged into same person for dramatic purposes ? Tom Vaughan-Lawlor plays 'McCabe' (not in the book) but, basing on some stills, it seems that he is important character in movie adaptation. And also, Pauline McLynn, despite that her character doesn't have a name on IMDb yet, I'm suspecting that she plays Mrs. McNulty, Roseanne's mother-in-law.
Anyway, one of my most anticipated movies of the year.
