This should be a good movie. Its good Kilmer, Walken, Sorvino, and Ray Stevenson.
Its the story of Cleveland mobster Danny Greene, an irishman who took on the Cleveland mafia and started a war that would have huge ramifications on the rest of the mafia families in the U.S.
It led to the eventual Commission case, which was the big case at the end of the movie Casino.
The book, To Kill The Irishman, its a solid read, i recommend it.
All the actors have been touting the script.
So if you like mob movies, this should be the next good one.
