Which 2016 film, set in the wizarding world, introduces magizoologist Newt Scamander as he arrives in 1920s New York with a briefcase full of magical creatures, some of which escape and cause chaos?

The film that perfectly fits this description is "Fantastic Beasts and Where to Find Them (Review)." Released in 2016, this movie transported audiences back to J.K. Rowling's beloved wizarding world, but with a fresh perspective. It introduces the endearing and somewhat awkward British magizoologist, Newt Scamander, portrayed by Eddie Redmayne, as he embarks on an adventure across the Atlantic.

The story unfolds in the bustling, jazz-age metropolis of New York City in 1926, a significantly different magical landscape than the familiar British Ministry of Magic or Hogwarts. Newt arrives with a deceptively ordinary-looking briefcase that, through magical means, houses an entire ecosystem of extraordinary creatures he has collected and studied during his travels. His intention is a brief stopover, but an accidental swap of cases with a No-Maj (the American term for Muggle), Jacob Kowalski, leads to several of these fantastic beasts escaping into the city.

The ensuing chaos, as Newt races to recapture his creatures with the help of Jacob and sisters Tina and Queenie Goldstein, forms the core of the film's plot. This cinematic experience serves as a prequel to the Harry Potter series, expanding the lore and history of the wizarding world decades before Harry's time. It marked J.K. Rowling's debut as a screenwriter, bringing her unique storytelling vision directly to the big screen and delving into the intricacies of magical society in America.
