THE GUEST directed by Adam Wingard, written by Simon Barrett, with Dan Stevens, Maika Monroe, Brendan Meyer and Sheila Kelley. A D Films release. 99 minutes. Opens Friday (October 17). For venues and times, see Movies. If I had to describe Dan Stevens in a word, it'd be "dashing." The former Downton Abbey star really does have that charming, handsome thing going on, which is why it's so jarring to see him do what he does in The Guest.
