As of April 7, 2022, there are a mere 92 days until Thor: Love and Thunder's July 8, 2022 theatrical debut - with no trailer in sight. As such, Thor 4 has broken the record previously held by Incredible Hulk (93 days) to become the Marvel Studios movie with the shortest trailer marketing window in MCU history (assuming that the Chris Hemsworth sequel maintains its July premiere).
Thor 4's Trailer Just Broke an Annoying MCU Record
