Romeo and Juliet is a tragedy written early in the career of playwright William Shakespeare about two teenage "star-cross'd lovers" whose untimely deaths ultimately unite their feuding families. It was among Shakespeare's most popular plays during his lifetime and, along with Hamlet, is one of his most frequently performed plays. Its plot is based on an Italian tale, translated into verse as The Tragical History of Romeus and Juliet by Arthur Brooke in 1562, and retold in prose in Palace of Pleasure by William Painter in 1582. Shakespeare borrowed heavily from both, but developed supporting characters, particularly Mercutio and Paris, in order to expand the plot. Believed to be written between 1591 and 1595, the play was first published in a quarto version in 1597. The play ascribes different poetic forms to different characters, sometimes changing the form as the character develops. John Gielgud's 1935 version kept very close to Shakespeare's text, and used Elizabethan costumes and staging to enhance the drama. In the 20th century the play has been adapted in versions as diverse as MGM's comparatively faithful 1936 film, the 1950s stage musical West Side Story, and 1996's MTV-inspired Romeo + Juliet.
