Undertaker: The Last Ride Documentary Promises To Be Essential Viewing For WWE Fans

The 55-year-old - whose real name is Mark William Calaway - has become a legend of wrestling, carving out a reputation as one of the all-time greats over several decades in the ring.

Now, in five-part series Undertaker: The Last Ride, fans will get an unprecedented behind-the-scenes look at the iconic wrestler as he prepares for the final chapter of his career.

The documentary features out-of-character interviews with the big man himself, as well as the likes of his wife and former Divas Champion Michelle McCool, and stars such as Vince McMahon, Shane McMahon, Paul 'Triple H' Levesque, John Cena, Roman Reigns, Batista, Ric Flair, Edge, Shawn Michaels, Mick Foley and many others.

A synopsis of the first episode 'The Greatest Fear' reads: "In this Sunday's premiere episode, Undertaker comes to terms with his own mortality as he prepares for what many believed to be the final match of his career against Roman Reigns at WrestleMania 33.

"Fans will get a rare glimpse into what led up to that moment, the pressure he puts on himself each year getting ready for WWE's annual pop-culture extravaganza, and much more.

"In addition, the episode looks back at the physical and emotional toll taken on Undertaker after his 21-year WrestleMania undefeated streak came to a shocking conclusion against Brock Lesnar at WrestleMania 30."

The review reads: "It is some of the more compelling content WWE has ever produced within its documentary series, and the timing of the release is perfect with people craving original content. If you are a fan of WWE's stories from behind the curtain, especially of The Undertaker, carve out time to watch Last Ride."
