There really isn't much of a resemblance until the Logan movies.
I didn't realize it until I was in Hartsfield Jackson in Atlanta a few years back and a kid walking with his mom through the concourse starts pointing and yells 'MOM!, MOM!, IT'S OLD MAN LOGAN!'
I spin around, looking for Hugh Jackman, thinking he's is right behind me. I didn't see anything but a mass of people and I turn back around and the kid had stopped in front of me and was just staring. His mom says 'You do look like Hugh Jackman'.
It could be worse.
I could look like Jack Klugman.
