Anthony Joshua Interview

HBO Boxing Insider Kieran Mulvaney goes one on one with Anthony Joshua. World Championship Boxing: Joshua vs. Klitschko airs Saturday, April 29 at 11pm ET/PT on HBO.

No matter what happens on Saturday, April 29 at London's historic Wembley Stadium, history will be made. Either Anthony Joshua will cement his place as "the next big thing" in boxing -- a title that his opponent, Wladimir Klitschko, 41, held nearly two decades ago -- or the most dominant big man of his time will reassume the throne, becoming only the second heavyweight to win a major title after age 40 (George Foreman, 45) and reclaiming the crown he lost so dismally to Tyson Fury in November of 2015.
