Bird Box's special effects makeup designer, Andy Bergholtz has shared some photos of the film's creature, which was almost shown but ultimately left out. Ever since its release, the film has proved to be quite a success for Netflix, as over 45 million people viewed it within the first week. The film has managed to become one of the year's most talked about subjects and has also spawned its own viral challenge (which the streaming platform has warned viewers about).

Directed by Danish filmmaker Susanne Bier, Bird Box is set in a post-apocalyptic world where members of society are offing themselves after looking at unseen supernatural creatures that appear as the victims' worst fears or regrets. The cast includes Sandra Bullock, Sarah Paulson, Colson Baker, Trevante Rhodes, Rosa Salazar, Tom Hollander, Danielle Macdonald, Milton Howery, and John Malkovich. Similar to John Krasinski's A Quiet Place, the survivors have learned to live by suppressing one of the five senses - except for this world it's not sound but sight. Bird Box never shows the creatures in physical form, but Bergholtz has shared some photos to give viewers a glimpse of what could have been.

Recently, Bergholtz shared some images (via Instagram) that reveal the deleted monsters possible design. In the description, Bergholtz mentions how the creature appeared differently to each victim, but this is what Bullock's character would have seen when corned by the creature in a nightmare sequence. He also discusses how the producers felt this design was relevant to the character's story arc and her resistance to motherhood.

While those images are certainly interesting, perhaps the decision to not show the entities was in the film's best interest, as it puts the audience in the same position as the characters. Not only are the entities not shown, but Bird Box doesn't provide viewers with many answers regarding the creatures. Hopefully, that will be explored further in a sequel if one were to happen. This latest addition to the Netflix original film library was adapted from Josh Malerman's debut novel of the same name, and for the most part, it sticks to the book. But the movie's final moments were slightly adjusted to fit with Bier's trend of hopeful endings, leaving the way open for a sequel.

Bird Box continues to be a hit for Netflix, and while there has been no official word of a follow-up, a sequel seems like a smart move. However, with many fans frustrated that the creatures were never exposed or properly explained, that should be a top priority if a sequel were to be announced. And if Netflix were to announce a sequel, it would be in their best interest to build interest around a guaranteed appearance of the creatures.
