The summer blockbuster period is upon us, which means that studios are already getting busy with production on next year's summer blockbusters. Among them is X-Men: Apocalypse, the next entry in director Bryan Singer's superhero prequel series, and David Ayer's supervillain team-up film Suicide Squad, in which the bad guys and girls of the DC universe have to learn how to play nice.
Singer has already begun promoting X-Men: Apocalypse on Instagram with a photo of James McAvoy getting his head shaved to play Professor X, and another of a mysterious group of fighters wielding bows and arrows in the forest. The latter image confused a lot of people, since the soldiers(?) were wearing suits and ties with no distinct military markings.
One possibility is that the child in that image was a young mutant, and Singer has since shared another set photo from the same location shoot which could back up that theory. The image shows 1st AD Josh McLaglen wielding a crudely-drawn cutout of an owl on a stick, which Singer explains in the caption is a "a mutant guided incoming owl."
One of the cap-wearing fighters can be seen just peeking in on the left edge of the image, confirming that this is from the same scene as the last set photo. One mutant from the comics with the ability to control animals is Lin Li, who lives at the X-Mansion after it becomes the Jean Grey School for Higher Learning, so Lin might be the child in the picture. Jean Grey (played by Sophie Turner) also has the ability to communicate with animals that possess high intelligence, but owls are pretty stupid even by bird standards.
