Introduced by a bumbling traffic cop (Pierluigi Marchionne), a group of unrelated people—some Italian, some American—share their time on-screen; their stories never intersect, and the only thing they all have in common is the location: Rome. There’s John (Alec Baldwin), a famous architect who miraculously travels back in time to chastise his younger self (known as “Jack,” played by Jesse Eisenberg) for his romantic blunders. Then there’s Leopoldo (Roberto Benigni), a middle-class Italian who finds himself, inexplicably, hugely famous. Allen himself plays Jerry, a retired opera director who decides to rekindle his career after hearing the rich, booming tones of Giancarlo (Fabio Armiliato), an undertaker with a natural knack for singing—but only in the shower. A number of other characters surface, their stories swallowed up by the sprawl of the film.
