He has no clear dramatic function that would justify his inclusion in a really great movie adaptation. He's whimsical and magical, and almost verging on silly. But also has the wisdom of the ages and the music of the spheres and deep emotional wells of ancient history and myth.
In our story, he has gone out to the lands of Rhûn, which we learn used to be sort of Edenic and green and beautiful, but now is sort of a dead wasteland. Tom has gone out there to see what's happened as he goes on his various wanderings.
