Heading into the weekend, “28 Days Later” was projected to open to $28 million to $30 million, which would be the best debut ever for a film in the undead series. “Elio” is expected to gross between $25 million to $30 million in its first weekend.

The summer's latest two event pics took advantage of the Juneteenth holiday by starting shows earlier in the day, but they still weren't able to topple 'How to Train Your Dragon' from the top spot.

The new post-apocalyptic zombie movie 28 Years Later pulls ahead of Pixar's family-friendly Elio in early box office numbers.
