Who played the role of Union Cane in Rocky V?

Michael Williams played Union Cane in Rocky V. Cane is introduced as the reigning heavyweight champion before Tommy “The Machine” Gunn challenges him for the title.

Williams was a real professional heavyweight boxer who competed under the ring name Mike Williams, nicknamed “Mercury.” His boxing background made him a natural choice to portray the fictional champion, even though Union Cane has only a brief role in the film.

In the story, Cane fights Tommy Gunn and is defeated in the opening round. That victory helps Gunn gain public attention, while Rocky Balboa becomes involved in training him after Rocky's financial troubles prevent him from continuing his own boxing career.

The character is sometimes confused with Tommy Morrison, the real boxer who played Tommy Gunn. Antonio Tarver appeared as Mason “The Line” Dixon in Rocky Balboa, while Tony Bellew played Ricky Conlan in the Creed films. Williams finished his professional boxing career with 22 wins, including 14 by knockout.
