There are a lot of actors that never reach the A List although they may have a few big roles. Increasingly, the nominees for Best Supporting are A List actors in a lesser role.
There are too many great performances in minor roles to fit within the number of nominees for Best Supporting Actor/Actress, so I propose another award for best character actor. There are no criteria for qualification other than a movie appearance. It is a unisex award. I envision it as the award that you give to an actor who has peaked and may never be eligible for a big award. We’ve come to accept their work as very good, but we’re so comfortable with them that we ignore their effort. They aren’t big enough to score an honorary Oscar in their 90s, but we oughta give them something because they’re in a ton of movies.
For same, I nominate the following for the first award: Kevin Bacon, Joan Cusack, John Turturro, John Goodman.
