10 Best Alien Abduction Horror Movies

10. Communion

Based on the book of the same name, Communion follows a novelist called Whitley Strieber (Christopher Walken) who's recently begun suffering visions involving bug-eyed aliens and surgical rooms. As his life falls apart, Whitley tries to make sense of what's happening to him before it's too late.

Although alien abduction stories have been around for decades, Strieber's purported story is directly responsible for popularising the Greys mythos, which has become a recognised staple in sci-fi. Communion feels more personal than the average horror flick, since these events are taken directly from Strieber's account of his purported visitation.

Walken perfectly conveys the disturbed author's anger and frustration, but most importantly, his shame. Strieber is too embarrassed to acknowledge the abduction initially, knowing he'll be humiliated by his peers. Despite the outlandish premise, moments like this are emotionally resonant, as they accurately demonstrate how a victim of trauma would behave.

Now, it goes without saying that the aliens themselves look hokey. (Walken himself laughed the first time he saw them.) However, Communion still proves to be a gripping and unsettling story, since the ensemble takes the subject matter deeply seriously.
