Reported by ERnest I Aguilar

Tonight at 8PM DST, WWE will present a one hour presentation titled Once in a Lifetime - The Rock vs John Cena, a behind-the-scenes documentary countdown-style show in preparation for WrestleMania.

The show was shot over several months and will air never-before-seen footage of the two training, at home, and at work as they prepare for one of the - if not the - biggest WWE match of all time at WrestleMania.

The show will have several airings throughout the week on all other NBC Universal properties - Syfy, Bravo, E!, Oxygen, G4, Style, NBC Sports Network, mun2, CLOO and Universal HD - leading up to WrestleMania on Sunday.
