Perhaps but I ' m inclined to think no . She seems like a generally shyish person in the sense that I don ' t think she enjoys that kind of attention in and of itself . I seem to remember reading that they offered for her to be Lily in the Mirror of Erised in the first film but she refused . That could ' ve been because she knew we ' d be seeing Lily more often and the part would demand acting skills that she may have felt were outside her wheelhouse . But also maybe she just wasn ' t interested in being in the films for any number of reasons . I do think it ' d be a little distracting ? But idk , I think Peter Jackson ' s cameos worked okay . M . Night Shayamalan sometimes gives himself a minor part with lines and that is much more distracting .
