Strong word-of-mouth and positive audience reception are anchoring trader consensus around an 11-13M second weekend for *Heart of the Beast*. The Brad Pitt survival thriller opened to a solid $20M domestically on September 25 amid stiff competition from an *Avengers: Endgame* re-release and other new titles, then posted a modest 58% drop from its first Friday with a $3.15M second Friday. An A- CinemaScore, 85%+ Rotten Tomatoes critic score, and appealing man-and-his-dog narrative have supported better-than-expected holdover performance, with analysts projecting a 35-45% overall weekend decline that lands squarely in the leading range. The market-implied 62.5% probability on 11-13M reflects this momentum, while the 37% on 9-11M accounts for potential further softening in a crowded fall marketplace.
