No one was expecting a blockbuster when Fantastic Four opened on August 7, but the final tally left even the most pragmatic of projections being overly optimistic. BoxOffice reports that the the 20th Century Fox reboot earned $25.69 million domestically, placing it well behind estimates for the weekend which started at $40m-$50m at the beginning of August before descending to $35m by opening day. Fantastic Four ended up #2 behind the second week success of Mission: Impossible - Rogue Nation, which earned $28.5m domestically.
BoxOffice estimates that the numerous negative reviews and "toxic early word of mouth" soured potential ticket-buyers for the film, capped by the tweeted-and-deleted comment by director Josh Trank claiming studio interference.
Putting it into context, the 2015 Fantastic Four pales in comparison to most all of the Marvel-associated films in the past twenty years. Even the 2007 Fantastic Four: Rise of the Silver Surfer outperformed Fantastic Four, with a $58.05 opening weekend.
To find a Marvel-related films that Fantastic Four outpaced, you'd have to look at 2012's Ghost Rider: Spirit of Vengeance (Sony) with a $22.1m weekend; before that, only New Line's Blade (1998) and Blade: Trinity (2004), Lionsgate's The Punisher (2004) and Punisher: War Zone (2008), Fox's Elektra (2005) and Universal's notorious Howard the Duck, which made about $5m its opening weekend in 1986.
