American actress Mercedes Ruehl was the daughter of a much-travelled FBI agent, who finally settled in Silver Spring, Maryland. After attending Catholic College in New Rochelle, Ruehl began her career in regional theatre, taking odd jobs during the many dry spells between engagements. For several years, it looked as though she'd be a permanent employee of the Baltimore Gas and Electric Company.
In the late 1970s, Ruehl began chalking up New York stage successes, notably {~I'm Not Rappaport}. She won an Obie for the off-Broadway {~The Wedding of Betty and Boo} and a Tony for {~Lost in Yonkers}. In films since 1979's The Warriors, Ruehl worked steadily but in relative anonymity until winning the Best Supporting Actress award for The Fisher King (1992). Ruehl wasn't able to fill houses as star of the lukewarm film version of Lost in Yonkers (1993), though she still is a most welcome supporting presence in such films as The Last Action Hero (1993). ~ Hal Erickson, All Movie Guide.
