DVD Menu Examples
1 - Warrior
Menu Design & Why producers chose to design them as they did
The design of the "Warrior" Menu uses a similar design to UFC Tale of the Tape cards as shown below.
This design is chosen because it is relevant to the subject, Warrior is a film about Mixed Martial Arts and UFC is a Mixed Martial Arts company.
The main menu as shown above has 3 images from scenes of the film, these pictures change every 10 seconds, and there are 6 changes meaning the menu loops every minute.
Functions and Elements in the Menu
There are 4 buttons on the main menu:
Play Feature - Does what the packaging says and starts playing the movie from the beginning.
English Hard of Hearing Subtitles - Gives the option to have subtitles On or Off.
Extras - Goes to the Extras Menu
Scene Selection - Goes to the Scene Selection Menu
The flowchart at the end shows a more detailed route of how the menu works and how the buttons connect.

Menu Structure
The structure of the 3 different menus are simple the Main Menu as previously said uses a Tale of the Tape design, and the 4 buttons along the bottom are clearly seen because of the contrast of white text on black background and are separated nicely so don't look to far away or too clumped together.
The Extras menu and Scene Selection Menu are transitioned to using a silhouette of an Octagon which is another reference to the subject of MMA as the sport take place in an Octagon. The Structure of the Extras Menu lists the buttons in another Tale of the Tape design on the silhouette as shown below:
The Scene Selection Menu's use the silhouette design as well but just list 6 scenes a page on the silhouette instead of a TotT design.
