In the play Hamlet, what does Polonious' fate have to do with him acting as Caecar in a University play?

Question

ACT 3-SCENE II. A hall in the castle.

To POLONIUS

My lord, you played once i' the university, you say?

LORD POLONIUS
That did I, my lord; and was accounted a good actor.

HAMLET
What did you enact?

LORD POLONIUS
I did enact Julius Caesar: I was killed i' the
Capitol; Brutus killed me.

Answer 1

Polonius is later stabbed behind a curtain by Hamlet in a case of mistaken identity. So the earlier remark is just dramatic foreshadowing and an ironic twist for interest. It did not directly cause his fate.
It is appreciated by the audience more the second time they see the play and is missed in the first experience by most viewers. These plays are written to be seen and enjoyed over and over again.

Answer 2

A little dramatic irony there...what the playwrights refer to as "foreshadowing."

Caesar was killed by the conspirators, of whom Brutus was one. Caesar knew Brutus, and considered him a friend (which is why he says: "E tu, Brute?" when Brutus stabs him). Similarly, Polonius is ultimately stabbed and killed by Hamlet, a young man whom he has known since Hamlet was a boy.

Answer 3

He played Caesar, and of course, Caesar dies, murdered by those who loved him. Hamlet kills Polonius by accident, ironically paralleling Caesar's fate. Brutus and Hamlet both kill seemingly without thinking. It's foreshadowing.
