Variety points out that Resident Evil: The Final Chapter did about $1 million on its opening night on the way to a $13.6 million opening weekend, so Hellboy is on track to improve on that.
Still, if Shazam! sees a second weekend drop of 50% or less, or even slightly more, it will still win the weekend box office.
To be fair, Hellboy was never projected to do as well as Shazam! the expectations has been that the movie will likely do about $17 million domestically this weekend and the Thursday night numbers would still put it on track to do about that much.
