Setting camera.ortographic = true should work?

I am probably missing something obvious. I tried to set a camera to orthographic mode:

public void Awake() { Camera.main.orthographic = true; Camera.main.orthographicSize = 5;

 // or...
 // GameObject cameraObj = GameObject.FindWithTag("MainCamera");
 // Camera camera = (Camera) cameraObj.GetComponent(typeof(Camera));
 // camera.orthographic = true;
 // camera.orthographicSize = 5;

}

...but the camera projection doesn't change (it is still "perspective"). What is wrong?

EDIT: Sorry for asking too fast. It works. For some reason the camera values aren't updated in the inspector if the camera is selected when you play. If a different object is selected before start playing, the camera projection is set to "ortographic" in the inspector when you select it. A small bug I guess...
