The nominees in this year's Oscar race for Best Supporting Actress, along with their respective nominated films, might be one of the most diverse groups of women to be recognized in recent years, and yet each and every one of the five ladies nominated has a thing or two in common in the fact that they all delivered scene-stealing and perhaps career-making performances in four very different films.

The only downside to the announcement of this category's winner come Sunday night is the fact that there can be only one. Of the very talented, worthy ladies up for Best Supporting Actress — Bérénice Bejo ("The Artist"), Jessica Chastain ("The Help"), Melissa McCarthy ("Bridesmaids"), Janet McTeer ("Albert Nobbs") and Octavia Spencer ("The Help") — here are our predictions for the category in 2012:

Who Will Win: Octavia Spencer, no question about it. For those who haven't been paying attention to this year's awards season, Spencer has already walked away with several impressive pieces of hardware. Her awards haul so far includes: the BAFTA for Best Supporting Actress, Golden Globe for Best Actress in a Supporting Role, the SAG Award for Outstanding Performance by an Actress in a Supporting Role, an NAACP Image Award and countless other accolades from critics groups.

Who Should Win: Spencer, followed very closely by Melissa McCarthy and her equally memorable performance in "Bridesmaids." The Academy very rarely recognizes comedies, so for our money, we're still pleased as punch that McCarthy received a nomination. Also, in a not-at-all-distant third place, 2011 breakout star Jessica Chastain deserves an award for being so good in so many movies this year. She was in seven, for goodness sake: "The Debt," "Take Shelter," "Coriolanus," "Tree of Life," "The Help," "The Texas Killing Fields" and "Wilde Salome."
