King Claudius is a fictional character and the primary antagonist of William Shakespeare's tragedy "Hamlet".
 He is the brother to King Hamlet, second husband to Gertrude and uncle and later stepfather to Hamlet.
 He obtained the throne of Denmark by murdering his own brother with poison and then marrying the late king's widow.
 He is loosely based on the Jutish chieftain Feng who appears in "Chronicon Lethrense" and in Saxo Grammaticus' "Gesta Danorum".
 There had never been an actual Danish King of that name.
Prince Hamlet is the title character and protagonist of William Shakespeare's tragedy "Hamlet".
 He is the Prince of Denmark, nephew to the usurping Claudius, and son of King Hamlet, the previous King of Denmark.

 By the end of the tragedy, Hamlet has caused the deaths of Polonius, Laertes, Claudius, and two acquaintances of his from the University of Wittenberg Rosencrantz and Guildenstern.
 He is also indirectly involved in the deaths of his love Ophelia (drowning) and of his mother Gertrude (poisoned by Claudius by mistake).
William Shakespeare's Hamlet is a tragedy, believed to have been written between 1599 and 1601.
 It tells the story of Hamlet, Prince of Denmark—who takes revenge on the current king (Hamlet's uncle) for killing the previous king (Hamlet's father) and for marrying his father's widow (Hamlet's mother)—and it charts the course of his real or feigned madness.
 "Hamlet" is the longest play—and Hamlet is the largest part—in the entire Shakespeare canon.
 Critics say that "Hamlet" "offers the greatest exhibition of Shakespeare's powers".
Over fifty films of William Shakespeare's "Hamlet" have been made since 1900.
 Seven post-war "Hamlet" films have had a theatrical release: Laurence Olivier's "Hamlet" of 1948; Grigori Kozintsev's 1964 Russian adaptation; a film of the John Gielgud-directed 1964 Broadway production, "Richard Burton's Hamlet", which played limited engagements that same year; Tony Richardson's 1969 version (the first in colour) featuring Nicol Williamson as Hamlet and Anthony Hopkins as Claudius; Franco Zeffirelli's 1990 version starring Mel Gibson; Kenneth Branagh's full-text 1996 version; and Michael Almereyda's 2000 modernisation, starring Ethan Hawke.
