It took me a long time to figure out who this picture of Fidel Castro reminded me of. The answer is, of course, Liam Neeson. This is helpful to know, as it throws us a bone in the sense that we now know the emphasis has to be on the shape of the nose and the brow--thick and nobby in the first case and convex in the second--the so-called topographical hook that Erin Burnett refuses to cough up.
(Other similar items include the faces of both the Statue of Liberty and Britney Spears (dead ringers, if you ask me, for each other) and the hood of the BMW Z-3, circa 2004.)
If we can nail these features down, then toss on a scraggly beard and a green military uniform with a brand new (leopard skin) pillbox hat, we are, as they say, golden.
