How can I make the player's head look in the direction of the mouse in a side scroller?

In a side scroller project (not the 2d one), how can I make the players head look in the direction of the mouse? For example, if the mouse was in the top right corner of the screen, the player would look towards the top right corner.

Ok, so this gave me a solid starting point, I had to work with the blueprint for quite a while to get it working properly the way I wanted it to but assuming anyone else having the same issue has some knowledge of blueprints this is a pretty good way to do it. Thanks.
