I'm using a FPS script for general navigation, but also have a 'tour' script which moves my player (and cam) around to some pre-defined views. In doing so, sometimes a 'roll' angle is introduced (for the nice view).
When the user moves the player (say, with mouselook or WASD), I want to remove any 'roll' that might have been introduced, leaving just pitch and yaw. Any ideas the best way to do this?

You can apply a corrective rotation that aligns the object's up vector with the world up vector. This can be easily done in Unity using Quaternion.FromToRotation().
That said, an even easier solution would be to use a control scheme that doesn't introduce perceived roll in the first place. (I don't know what control scheme you're using currently, so I can't be much more specific than that.)

Here is what I'd probably try:
I haven't actually tried the above myself, so it's somewhat speculative. But, it's probably what I'd try first.
