Quintessential innocent man on the run plus love interest from Hitchcock. Whilst he subverted this trope in Stage Fright, it has arguably been his safety blanket to fall back on. Whilst this isn't an outstanding example, it's a solid film nonetheless.
The best thing about this is most certainly the chemistry and charisma of the two stars. It almost lifts this to a more notable regard. Outside that though, the whole murder is a little poorly communicated. Once again, it has shaky beginnings (despite an eyecatching lighthouse scene). There are certainly pacing issues as well. The film works best when we forget the why and just leave our brain behind and get caught up in the emotions and suspense of the piece.
Slightly underappreciated in the annals of Hitchcock (you almost never hear about it), but there is little here to really sell this as a must see. An enjoyable deep cut for Hitch nuts.
