The first trailer for The Eternals was revealed at the Marvel Studios panel at the Brazilian Comic-Con Experience 2019. While the video itself is not available for online streaming, IGN Brazil was there to break down what was shown. The footage starts with a door opening. An old man says he "missed them" to the beings before him -- the Eternals, with Ikaris (Richard Madden) out in front -- and asks them to make themselves at home.
