Philip Rivers always looked familiar to me, and now I think I know why.

I spotted River's look-alike while watching "Tango & Cash", that brilliant 1989 movie with Sylvester Stallone and Kurt Russell.  The character Face looks just like him!  Remember the scene in the prison laundry?

Ray Tango: Oh shit, it's Conan.
Gabriel Cash: What?
Ray Tango: It's Conan.
Gabriel Cash: Are we gonna get F.U.B.A.R now?
Ray Tango: What the hell is F.U.B.A.R?
Gabriel Cash: You'll see.
Face: Real bad ass cops. You don't look so tough now, do you? DO YOU, YOU FUCK? Out on the streets, this pig with his cop friend, broke my ribs, my leg and my jaw.
[tsks at Tango]
Gabriel Cash: You broke that jaw?
Ray Tango: He deserved it.

The resemblance, it's uncanny!!!

In full disclosure, this diary was meant as a joke, so hopefully no one takes it seriously... and if anyone knows of any other look alikes, please throw them in the comments! :)
