Star Estimator

What do these celebrities have in common?

One, they're all listed in the celebrity list of Analogia's Star Estimator site.
Two, they were shown as the results of my pics, which Analogia said matched me.

I really don't see any resemblance, so either they need more celebrities on their list, or need to somehow fine-tune their matching program.

This is my most recent result, which actually used the same photo as the second one I tried. It's slightly different from before, where Hugh Jackman has been removed, Tom Cruise moved into the second match, and Ricky Martin is added in.
