Avengers: Endgame was on the market for less than 20 hours before hitting a stunning box office landmark. In fact, in just 17 hours, the final installment of Marvel’s Infinity Saga made $100 million, with $60 million of that being generated during Thursday night preview showings. The previous record holder for reaching that threshold the quickest was Star Wars: The Force Awakens, which took a whole 21 hours to make that much money. Given that this is the culmination of a 22-movie shared universe spanning 10 years, and that it’s been getting rave reviews from critics, Endgame is unsurprisingly on its way to more massive box office totals this opening weekend.

Tracking suggests the film could have the biggest opening day of all time, with estimates going as high as $150 million, contributing to a “cautious” projection of $300 million in domestic intake alone. (Deadline is pushing that number up to as much as $330 million.) Around the world, Endgame has already made more than $300 million at the international markets, meaning it will easily clear the half-billion dollar mark by Monday morning.
