The 23 actors who have gotten the most Oscar nominations without winning one

• The Oscars have repeatedly nominated and neglected numerous actors.
• They include Amy Adams, Glenn Close, and Bradley Cooper, who all lost Oscars this year.

Each year, deserving performances lose out in the Oscars' best acting categories. But there are a handful of great actors that the Academy has repeatedly nominated and neglected. 

Both Amy Adams (six nominations) and Glenn Close (seven nominations) lost on Sunday to Regina King and Olivia Colman, respectively.

Both Bradley Cooper and Willem Dafoe were nominated for their fourth acting Oscars this year (Cooper has a total of seven nominations for producing "American Sniper" and "A Star is Born," and writing "A Star Is Born"). Both lost in the best actor race to Rami Malek for his performance in "Bohemian Rhapsody."

And all-time great Peter O'Toole, unfortunately, had it even worse.

Here are the 23 actors who have been nominated for at least four Oscars without winning once:
