Silver Vision has released the official trailer for WWE’s upcoming DVD and Blu-ray title Rock vs. Cena – Once in a Lifetime.

“In the week leading up to WrestleMania XXVIII, a one-hour documentary aired on NBC Universal in America called ‘Once In A Lifetime: The Rock vs. John Cena’. This DVD collection is an expanded version of that documentary – giving the full one-year story of the build up to this epic match – from the very first promo.

“It also gives an insight into the preparation of body and mind that these two competitors went through before they met in the ring on April 1 in Miami. Once in A Lifetime explores the iconic Superstars long, emotional paths toward their match, and gives viewers a glimpse into The Rock and John Cena’s daily lives, training regiments, and the personal choices and histories that led them to the defining moment of their careers.”

The three-disc DVD and two-disc Blu-ray set will be released in the United States on Sept. 11.
