When it came to deciding the worst movie on this very niche but Ford-focused list, there was only one title that fit the bill. Adapted from the comic book of the same name, "Cowboys and Aliens" saw Ford as a gruff, excessively grumpy cattleman who runs into trouble when a stranger (Daniel Craig) stumbles into town, being chased by aliens. The director of "Iron Man" is helming a project starring James Bond and Han Solo as they both fight aliens in the Old West. Unfortunately, far too much. Ultimately, a movie that should've made you want to be a cowboy fighting aliens leaves you wondering if you'd rather do anything else instead.
