He developed his costume and assumed the part practically 30 yrs ago that would direct to appearances on "The Day-to-day Show" and "Jimmy Kimmel Live!".
His body was found in clothing dustbin, used for clothing donations, the law enforcement sources said.
"Chris was a sweet guy who appeared on our show many times and was well-liked by everyone at Jimmy Kimmel Live".
The cause of his death is still unknown. "We will miss him", said host Jimmy Kimmel.
The Super Museum, a museum dedicated to Superman history located in Metropolis, Ill., confirmed the news in a Facebook post. The Superman Super Site extends our deepest heartfelt condolences to Dennis's family and loved ones during this hard time of mourning.
Following an assault in 2016 which rendered him homeless and his Superman costume being destroyed, Dennis started a fundraiser campaign which resulted in him being able to get back on his feet and acquire a new costume so he could return to Hollywood Boulevard as the Man of Steel once again.
Dennis was one of many performers who roam Hollywood's Walk of Fame dressed as iconic pop culture characters. Chris has had many struggles and ups and downs over the years. For almost three decades, Dennis had worked as a street performer donning the classic red-and-blue Superman outfit, in part due to his physical resemblance to Christopher Reeve.
"We've recognised Chris for lots of several years", the statement ongoing. "We hope that he is at peace now", the statement continues. Though he had tremendous appreciation for the character, Dennis clearly loved bringing smiles to the untold thousands of people who've crossed paths with him in Hollywood.
