Should Tom Bombadil have been in the movies?

[Arwen_Evenstar]

In a book somewhere it said that PJ was thinking of putting in a scene where the Hobbits were walking through the forest when they saw a blue hat and heard singing and got scared and ran off, may have been a movie guide of some description, but he didnt for some reason or another...maybe because it would confuse people who hadn't read the books....i dno....backup would be apreciated!
