Mercutio: "Ask for me tomorrow, and you shall find me a grave man." His dying line is a pun!
Friar Laurence's Get A Hold Of Yourself Man speech to a hysterically suicidal Romeo in Act III Scene II; he reminds Romeo that he was lucky to be banished instead of punished by death, lucky to have killed Tybalt when Tybalt tried to kill him, and killing himself will essentially kill Juliet.
Where be these enemies? Capulet, Montague? See what a scourge is laid upon your hate, that heaven finds means to kill your joys with love. And I, for winking at your discords too, have lost a brace of kinsmen. All are punish’d.
1936 film
The 1936 film features the only sword fight that Basil Rathbone got to win in his acting career, despite being a far more skilled fencer than many of his opponents.
