Okay so I just looked up Jason Isaacs at imdb.com and he is British (learned something new). He was born in Liverpool.
Oh interesting news.
Pre-production of Harry Potter and The Order of the Phoenix.
Release year: 2007
Three guesses (and the first two don't count) who he plays.
Although he is in GoF and I honestly don't recall Lucious being in the book. Someone please help me on this.
Oh wait just answered my own question. He's at the end with the other Death Eaters.
That sucks that we only get to see him at the end. Jason Isaacs is one of my fave actors. He he.
