Radagast the Brown

[Imladris]

Well, I don't have the time and go find the pic, but if he was supposed to be in the movie and was cut, I can give at least one good reasons why he was.

Imagine a Tolkien Newbie seeing FotR in theatres. Suddenly, it is cut to an old man with moths circling around him and then it cuts back to Orthanc or whatever. Who is he? Why doesn't he appear for the rest of the movie? Why was he even there? The way you're putting it, there would be no name or chance of introduction. If they wished to have him send Gandalf to Saruman, that would take even more screen time, yet another actor to play, etc. Remember, PJ and crew didn't have all the money in the world.

That's why. Even thought it would have been nice for Tolkien fanatics like us, it really would't have been possible.

Another reason is that Radagast doesn't forward the plot at all. He's just kind of there.
