Keanu Reeves and the cast of ‘John Wick: Chapter 4’ take ET inside the making of the action franchise’s latest installment. Returning actors Laurence Fishburne, Ian McShane and, in his final ET interview, the late Lance Reddick try to explain why fans obsess over the ‘John Wick’ universe. Fresh faces include Bill Skarsgård, Donnie Yen, Hiroyuki Sanada and Rina Sawayama, who break down the new fight scenes and how their characters fit into ‘Baba Yaga’s journey. Shamier Anderson also jokes about working with the ‘cuddly’ stunt dogs behind the scenes. Plus, Reeves and director, Chad Stahelski, look ahead to Ana de Armas and Len Wiseman’s ‘Ballerina’ spin-off. ‘John Wick: Chapter 4’ is in theaters now.
