Crackle Plus will debut a original documentary that follows the career of former heavyweight boxing champion Lennox Lewis, the network said Tuesday.

The series, Lennox Lewis: The Untold Story, debut Oct. 15 and follows the life of the three-time champion through never-before-seen footage from his personal archives, said representatives from the streaming service. Narrated by Dr. Dre, the documentary also features interviews with Lewis as well as such other heavyweight champions as Mike Tyson, George Foreman and Evander Holyfield, said the service. 

“We are proud to bring this inspirational story of Lennox’s historic boxing career to Crackle,” said Richard De Croce, SVP of Programming at Crackle Plus in a statement. “We know our audience will appreciate Lennox’s passion and determination to overcome the obstacles he’s faced and reach his dreams both in and out of the ring.”

HBO will gather several boxing legends to discuss the May 2 Floyd Mayweather-Manny Pacquiao fight as part of new special debuting later this month.

The 30-minute special, Mayweather/Pacquiao: The Legends Speak premieres April 25 and features HBO boxing analyst Max Kellerman interviewing a number of ex-boxing champions to size up the matchup between arguably boxing’s two biggest pay-per-view draws.

Kellerman will interview former Mayweather and Pacquiao opponents Oscar De La Hoya, Shane Mosely, Miguel Cotto and Ricky Hatton about how to prepare for both fighters, said the network. In addition, the show will feature a panel of ex-boxing champions including George Foreman, Lennox Lewis and Bernard Hopkins discussing the upcoming event.
