Jack Nicholson famously redefined how much the bad guy can get paid in a Hollywood film but which of the Batman villains have the most to say? Well they were all quite roundly beaten by Danny DeVito's Penguin with nearly 150 lines in Batman Returns. And Ledger's Joker had a very similar number of lines to Nicholson. And as pairs go, Freeze and Ivy had more to say than Two Face and the Riddler (unfortunately).
I've not included Catwoman because she's more neutral than bad and have skipped the bit-part bad guys like The Scarecrow but otherwise I've tallied up every time a villain spoke in the scripts of all the films.
