If the studio is even considering taking Warm Bodies further, it seems probable that they’d take the struggles of the more recent book adaptations into account when crunching the numbers.
Summit’s parent company Lionsgate saw massive success with the Hunger Games adaptations, but even those movies saw declining box office numbers with the last two films.
That said, Summit was still cashing major Twilight Saga checks back when Warm Bodies was acquired for an adaptation.
The years since have not been quite as prosperous for young adult adaptations, as evidenced by the returns on Ender’s Game and the Divergent series at the box office.
