Mamma Mia! will be presented in widescreen 1080p video and 5.1 DTS-HD Master Audio.

A new twist is being put on commentaries with a Blu-ray exclusive sure to turn heads. With Mamma Mia!, it will be possible to record a video commentary while watching the film and then share that commentary with friends.

In addition to BD-Live access and U-Control (what are these?! See definitions below), other confirmed features are as follows with more to be announced. 

• My Mamma Mia! Commentary – Record your own video commentary while watching the movie and share it with friends (Blu-ray exclusive)
• BD-Live (Blu-ray exclusive) – BD-Live allows your Blu-ray player (if compatible) to access additional content via an Internet connection. Some already revealed BD-Live features include downloading related movie trailers, sending a ringtone to your cellphone, and playing interactive online games.
• On-screen lyrics for 22 songs
• Gimme! Gimme! Gimme! Music Video
• The Making of Mamma Mia!
• Becoming a Singer
• On-Location
• U-Control – U-Control allows for a variety of pre-encoded materials (video, audio, text overlays, etc.) to be stored on disc, and then accessed on-the-fly by users during playback. Multiple audio streams can be encoded on a disc and "mixed live" by the player for integrated supplemental audio content, picture-in-picture video streams can be displayed simultaneously, and even graphic overlays can be "mapped" to specific objects on the screen.
• And more to come…
