Transformers: Dark of the Moon is one of over 30 titles that was mixed using Dolby Surround 7.1 for the theatrical release. The current Blu-ray release uses a 7.1 Dolby TrueHD mix.

Russell, re-recording mixer, Transformers: Dark of the Moon. “The team did a tremendous job on the original 7.1 mix for Transformers: Dark of the Moon and we are excited fans will now be able to get the cinematic 7.1 surround sound experience with Dolby TrueHD 7.1 on the Blu-ray Disc.” We have three copies of Transformers: Dark of the Moon on Blu-ray to giveaway.
