5. Richard Jenkins in The Shape of Water - Jenkins gives a wonderful performance very much as the type of truly "supporting" supporting performance by offering just bit of extra humor, warmth and emotion to the film.
Best Scene: Repeating the signs.
4. Christopher Plummer in All the Money in the World - Plummer's post-last minute work here stands on its own, past the unorthodox nature of his casting, through his captivating portrayal of the world's richest man who he brings to life as indeed a commanding miser, but with a sense of humanity even within his most despicable behavior.
Best Scene: Fletcher confronting Getty.
3. Willem Dafoe in The Florida Project -Dafoe delivers one of his best performances through his earnest and always genuine portrayal of decent man trying to keep his optimism through much adversity. It's quietly poignant portrayal of an honest warmth within a rather harsh environment.
Best Scene: Dealing with a pedophile.
2. Woody Harrelson in Three Billboards Outside Ebbing, Missouri - Harrelson grants his character here a notable charisma and brings out the best in his film's humor. He goes further though in giving a rather heartbreaking portrayal of a man facing his own mortality.
Best Scene: Interrogation room.
1. Sam Rockwell in Three Billboards Outside Ebbing, Missouri - Good Predictions Mitchell, Giuseppe, Tahmeed, Luke, Jackiboyz, Maciej, RatedRStar, Omar, Robert, GM, Michael McCarthy, Anonymous, Matthew C. Well for me Rockwell tops this fantastic year for supporting actor nominees. Rockwell as expected brings such an energy through his performance, and where Harrelson excels in the verbal humor though Rockwell does that too, Rockwell is dynamite with the physical humor around his character's buffoonery. Rockwell's work is most remarkable though in successfully delivering his character's arc from a terrible man to a broken man finally starting to see his mistakes.
