Taken from the real case files of legendary paranormal investigators Ed and Lorraine Warren, 2013's The Conjuring sees the Perron family's quiet home life disturbed by malevolent spirits, who take particular pleasure in taunting their young children. It seems like the disruption may not have ended there, however, as lead actor Patrick Wilson, who portrays real-life demon hunter Ed Warren in both the movie and its 2016 sequel, recounted how one of the child actors on The Conjuring got mysteriously injured on set.
Joey King, who played Christine, ended up covered in strange bruises "all over her body" after just a couple weeks of shooting. Wilson explained to the UK's The Independent newspaper that King hadn't been doing any stunts (child actors don't usually do stunts, to be clear), nor had anything hit her over the course of filming. They just kinda … showed up.
Although the marks subsequently disappeared, Wilson still felt weird about using the anecdote during press for the movie (even though he admitted it totally fit the bill). Wilson also confirmed, over the course of the chat, that his own home is haunted, noting that "I've heard people on two different occasions say they've heard kids' laughter in the middle of the night, in my house. And that used to freak my wife out." But that's another story entirely.
