My favorite long speach from Pacino is the Inches Speech in Any Given Sunday. In fact, this is my favorite line from the movie.
"Now I can't do it for ya, I'm too old. I look around, I see these young faces and I think, I mean, I've made every wrong choice a middle-aged man can make. I've pissed away all my money, believe it or not. I chased off anyone who's ever loved me. And lately, I cant even stand the face I see in the mirror."
