Josh Hartnett Shocks Fans With Surprise Post

Josh Hartnett shocked fans with a surprise social media post.

Hartnett has reappeared on the Instagram account of his new movie Fight or Flight.

One video post makes fun of his absence from social media. "Me promoting my film before ghosting social media for another 10 years," the caption on the video, which shows part of Hartnett's face, says.

"When your team insists on a social media content day to promote your new film, Fight or Flight (in theaters May 9), but you don’t get any of these viral trends," the post continues.
