Projections are all over the place for Danny Boyle's long-awaited '28 Days' sequel as 'Elio' braces for a soft opening, and possibly the lowest in the storied studio's history.

How will a plucky, alien-obsessed tween and an undead army fare at the box office against a lovable, fiery dragon? That’s the looming question as Disney and Pixar’s intergalactic animated adventure “Elio” and Sony’s post-apocalyptic thriller “28 Years Later” prepare to face off against Universal’s live-action “How to Train Your Dragon” remake in North America.

The movie had stronger-than-expected ticket sales over the weekend, becoming the third PG-rated, live-action hit in three months.
