Although he first copyrighted the text in June 1918, O'Neill continued to revise the play throughout the rehearsals for its 1920 premiere.

[1] His first full-length work to be staged, Beyond the Horizon won the 1920 Pulitzer Prize for Drama.

[2] Beyond the Horizon was revived on Broadway at the Mansfield Theatre on November 30, 1926 and closed on February 5, 1927 after 79 performances.

The play was adapted for television and broadcast on PBS Great Performances series in July 1975, directed by Rick Hauser and Michael Kahn.

That play emerged from O'Neill's association with the Provincetown Players, one of many so-called 'little theaters' that developed in the 1910s to provide alternative fare to commercial drama of the time.
