3. Casanova (2005)
What better stage to set a mistaken identity comedy than a masked ball at Venice’s Carnevale? With stars Heath Ledger and Sienna Miller supplying plenty of wit and charm, this costume romance is an utterly delightful romp of a film with such a fun, tangled web of multiple mistaken identities — including Jeremy Irons’ Grand Inquisitor mistaking a rotund lard merchant for the infamous seducer of women, a brother-sister duel switcheroo, and Miller’s headstrong Francesca Bruni falling for a man she doesn’t know is Casanova, a man who stands for everything she writes against (under a pseudonym that, of course, adds to all the confusion).
