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.
The massive opening battle in the 1968 film, with practically every single servant fighting. One guy is even seen fighting three opponents at once! And Lord Capulet gets on the action too, wielding his gigantic longsword and managing to cut down one Montague who tries to attack him.
Tybalt's entrance in the Baz Luhrmann film. Badass personified.
Tybalt's "I AM FOR YOU" just before the fight with Mercutio was probably the most badass point in the whole play.
Mercutio's most (in)famous line: "A plague o' both your houses!" after his swordfight with Tybalt he shouldn't have died from.
