The poster promotes the film "Locked" by showing the stars, creators, tagline, and title. It uses shades of white and grey to give a real and gritty feel. The key image depicts the main character Ryan protecting Jess as a hand reaches for a key, suggesting a search for freedom. Though realistic looking like a photo, the background is edited, implying the film has a realistic storyline with little effects. The film title is in the largest, most central font to stand out as most important, while the tagline and actor names are prominently displayed in darker tones to contrast the light background. The studio and release status are listed at the bottom.
