...there is that lovely little deleted scene that I always wish had been left in, the 'What about Sonny, what about Sicily...??' exchange between Vito & Michael. It indicates that it is Michael who may be more interested in vengeance...and Vito shows him how to get it, but never actually breaks his own word to the other Dons.
Exactly right Apple.
After Michael asks that question of Vito, his father's reply is "
I swore that I would never break the peace." to which Micheal eventually replies "
Well -- you gave your word that you wouldn't break the peace, I didn't give mine. You don't have to have any part -- I take all responsibility."
A deleted scene that I strongly feel
needed to be left in the movie!
