susan bones & green eyes

[skyw1ngs]

Hey there. I'm new so I don't know if this has been discussed 
earlier.

Just wondering if anyone else was a bit annoyed with Chris Columbus 
(as good as he was directing PS/SS and I'm sure CoS) when he just 
had to keep including his daughter who played Susan Bones in scenes 
a Hufflepuff wasn't really supposed to be in? For example, in 
Snape's class, wasn't Gryffindor paired with Slytherin?

Also, what's the story with Harry's green eyes? He's always had 
green eyes in the books but in the films they're blue and, as far as 
I can see, only turn green sometimes. Was that an error? 
Inappropriate to get a young kid to wear contacts and too expensive 
to change them digitally in every scene? Just curious to know some 
behind the scenes tid bits.
