First I tried the poster child for Mortal Engines but it told me "Face not detected."

Next I tried Christopher Reeve, but the computer told me the photos were "inappropriate."  I guess he's too sexy for Microsoft?  Lol!

Last, I tried Chris O'Donnell's Robin character from "Batman and Robin."  I selected a current picture of Chris because I was getting bored and didn't feel like searching for a pic from the same time period (1997.)

In each case, I cropped the picture so that only the face was uploaded.

Here are the results:
