API - How to get an existing component?

[RickPalo]

I have a GameObject (named "Player") with an attached SplineController.  Based on user input, I want to start/stop movement along the spline.  I tried to reference the controler

Code:

controller = GameObject.Find("Player").GetComponent("SplineController")

but I get an error that the result is a Component instead of a SplineController.  What is the correct way to access an object that already exists?
