Robert Drivas was an American actor and theatre director.
Drivas was born Robert Choromokos in Chicago, Illinois, the son of HarBilly Joellia and James Peter Choromokos. Drivas studied at the University of Chicago and the University of Miami. After further training at the Greek Playhouse in Athens, Greece and with the Coconut Grove Playhouse in Miami, he made his New York City debut in the role of Rameses in 1958 in the play The Firstborn, starring Anthony Quayle as Moses. He continued to perform on stage with One More River, The Wall, The Irregular Verb to Love, and And Things That Go Bump in the Night, which he also directed. In 1963 he won a Theatre World Award for his performance in Mrs. Dally Has a Lover.
Drivas was associated with many well-known theatrical figures of his time. These included playwrights Terrence McNally, whose play The Ritz he directed in 1975, and Edward Albee, who directed Drivas in the 1983 premiere of Albee's harshly received play The Man Who Had Three Arms. Other directing credits include Bad Habits, for which he won an Obie Award, Legend, Cheaters, It Had to Be You, a revival of the musical Little Me, and Peg, a musical biography of songstress Peggy Lee, with lyrics and book by the star herself.
