And my favorite "Godfather" look - Sollozzo's face when he tells Tom Hagen, "Let me worry about Luca" (already knowing that Luca Brasi was dead):
Four great choices, SC!
Using Al Lettieri as Sollozzo was one of the innumerable casting master-strokes of GF and II. Although Sollozzo is a pivotal character in GF, he actually has a small amount of on-screen time. But Lettieri is so absolutely letter-perfect that he's unforgettable. He's something like Lee Marvin: the coarse, thuggish look and character coupled to a cultivated speaking tone. Plus, in Lettieri's case, his facial expressivness.
