Context paragraphs:
Romeo + Juliet: William Shakespeare's Romeo + Juliet (shortened to Romeo + Juliet) is a 1996 American romantic drama film directed, co-produced, and co-written by Baz Luhrmann, co-produced by Gabriella Martinelli, and co-written by Craig Pearce, being an adaptation and modernization of William Shakespeare's tragedy "Romeo and Juliet".  The film stars Leonardo DiCaprio and Claire Danes in the leading roles of Romeo and Juliet, who instantly fall in love when Romeo crashes a party and meets her, despite their being members of the Montague and Capulet family; Brian Dennehy, John Leguizamo, Pete Postlethwaite, Paul Sorvino, and Diane Venora star in supporting roles.

Shakespearean tragedy: Shakespearean tragedy is the designation given to most tragedies written by playwright William Shakespeare.  Many of his history plays share the qualifiers of a Shakespearean tragedy, but because they are based on real figures throughout the History of England, they were classified as "histories" in the First Folio.  The Roman tragedies—"Julius Caesar", "Antony and Cleopatra" and "Coriolanus"—are also based on historical figures, but because their source stories were foreign and ancient they are almost always classified as tragedies rather than histories.  Shakespeare's romances (tragicomic plays) were written late in his career and published originally as either tragedy or comedy.  They share some elements of tragedy featuring a high status central character but end happily like Shakespearean comedies.  Several hundred years after Shakespeare's death, scholar F.S. Boas also coined a fifth category, the "problem play," for plays that don't fit neatly into a single classification because of their subject matter, setting, or ending.  The classifications of certain Shakespeare plays are still debated among scholars.

Revenge tragedy: Revenge tragedy (less commonly referred to as revenge drama, revenge play, or tragedy of blood) defines a genre of plays made popular in early modern England.  Ashley H. Thorndike formally established this genre in his seminal 1902 article "The Relations of Hamlet to Contemporary Revenge Plays," which characterizes revenge tragedy "as a tragedy whose leading motive is revenge and whose main action deals with the progress of this revenge, leading to the death of the murderers and often the death of the avenger himself."  Thomas Kyd's "The Spanish Tragedy" (c.1580s) is often considered the inaugural revenge tragedy on the early modern stage.  However, more recent research extends early modern revenge tragedy to the 1560s with poet and classicist Jasper Heywood's translations of Seneca at Oxford University, including "Troas" (1559), "Thyestes" (1560), and "Hercules Furens" (1561).  Additionally, Thomases Norton and Sackville's play "Gorbuduc" (1561) is considered an early revenge tragedy (almost twenty years prior to "The Spanish Tragedy").  Other well-known revenge tragedies include William Shakespeare's "Hamlet" (c.1599-1602) and "Titus Andronicus" (c.1588-1593) and Thomas Middleton's "The Revenger's Tragedy" (c.1606).
