Was he the Boss of the Tattaglia Family?? Cause i remember Luca Brasi went to a meating with a man who so called himself Bruno Tattaglia and Virgil Sollozo.. But then later on in the movie,after Sonny gets killed, Don Corleone in the meeting with the other heads fo the five family's introduces evryone and names Phillip Tattaglia.. so can someone explain this to me cause im realy comfused

Phillip Tattaglia was the head of the Tattaglia family. Bruno was his youngest son (I think he was the youngest) and dealt directly with the Tattaglia's prostitution business (a lot of the girls at his nightclub were also hookers, I guess)

anyone know the name of the actor who plays Bruno?

Tony Giorgio

Phillip Tattaglia was the head of the family, Luca did go to meet Bruno who was his son - Sonny had Bruno killed to get back at the family after Don Vito was shot.

Tony Giorgio, I read somewhere, was a circus freak, and by freak I mean entertainer, not bite-the-heads-off-chickens freak.

alright so this is how Phillip Tattaglias son got killed, now i understand that part, alright thank you all.. hehe he is realy a circus freak?

The book gets into this a bit more. Luca starts seeing a Tattaglia hooker and voices his displeasure about being w/the Corleone's (per Don Corleone's request). The hooker relays the information to Bruno, who arranges the meeting between Sollozzo & Luca in the nightclub.
