Who is playing seth and Leah in new moon?

As far as I know, no one has been cast for the role of Seth or Leah. But they aren't mentioned a whole lot in New Moon, only as Harry Clearwaters kids, I think. In Eclipse they become more important.

I'm not sure who they will pick, personally I think they should leave all the cast members in the parts they had in the first movie.

Leah wont appear in New Moon.
I'm not sure about Seth...

i dont think they are going to put seth and leah in new moon but they will appear in eclipse! xD

I think Tyler Posey should play Seth.
And for Leah.. I think Megan Fox should play her.

Julia Jones is set to play Leah and BooBoo Stewart will play Seth. Heres a pic of BooBoo...

theres no leah in new moon! she dosent appear throughout the whole movie, BUt Julia Jones is playing her in the upcoming movies, and seth is played by Boo Boo stewart!
