I thought one of the men involved in the shootout right after the assassination attempt on Frankie Pentangeli looked a lot like Willie Cicci. He was the one who got hit by the car. Can anyone fill me in on this?

That is him, and he gets shot too.

Thanks Tony! I thought that was him, but I thought he was Clemenza's button man, and ultimately under Michael Corleone.

He was one of Clemenza's button men. He was the one who shot Cuneo in the revolving door. After Clemenza died, Frankie took over operations in New York. I guess Cici then became his bodyguard.

he was also a bodyguard of sonny - he's with sonny when he is kicking carlo's ass

Yeah, I knew it was him that hit Cuneo in the revolving door, but I don't remember him with Sonny. Darn, guess I'll have to watch it again.

Yea he was moving the kids away from Sonny kicking Carlo's ass. If you remember he was the one who took the gun away from Tessio.

I do remember him taking Tessio's gun. I think he said "Excuse me, Sal... "

Wasn't he the one who was reading a book when Sonny came out of Lucy's apartment and to whom Sonny said the famous line "Save it for the liberry?"

Look for Cicci in two other places:
1. When Michael and Sonny are embracing to say goodby before Michael goes to kill McCluskey and Sollozzo, Tessio gestures to Cicci to follow him in the background.
2. Cicci is standing around the piano (played by FFC's father) during the Five Families War of 1946 montage.

Look for Frank Sivero, who played young Genco in II, in that scene.
