Although the lead actor was phenomenal, critics believe that the supporting cast was the real fulcrum [ˈfʊlkɹəm] of the show.

fulcrum
noun [ˈfʊlkɹəm]

In technical use, fulcrum refers to the support on which a lever moves when it is used to lift something. In figurative use, fulcrum refers to a person or thing that makes it possible for something to function or develop, or in other words, one who plays an essential role in something.

Fulcrum, which means "bedpost" in Latin, comes from the verb fulcire, which means "to prop."
