Invisible VFX can be just as important to the success of a film as the splashy, show-offy stuff. Case in point: this VFX breakdown for Union VFX’s work on Three Billboards outside Ebbing, Missouri, which featured a lonesome deer, Frances McDormand chucking Molotov cocktails from an upstairs window, and some seriously misplaced dental work among shots requiring seamless augmentation. Consider a mild spoiler warning in effect, and remember that all included footage is © Fox Searchlight Pictures.
