The line comes from The Truman Show (1998), where Jim Carrey plays Truman Burbank, a man whose entire life is a secretly televised reality show. Each morning Truman greets his neighbours with the film's famous hello, and the moment became one of Carrey's most quoted scenes. Brazilian and Portuguese-speaking fans adopted the dubbed version, 'bom dia, boa tarde, e boa noite,' turning it into a staple of WhatsApp audios, morning posts and reaction memes. It endures because it captures Truman's unbreakable optimism in a single cheerful sentence.
