"Alien: Romulus" made a major impact on the domestic box office with $41.5 million, marking the second-best opening in the history of the "Alien" series. Those ticket sales were enough for the newest chapter in Disney and 20th Century's sci-fi horror saga to bring to a close the three-week reign of "Deadpool & Wolverine," which just overtook "Joker" as the top-grossing R-rated film in history with $1.14 billion.
