Lyric Theatre Belfast, the venue where he performed the leading role in the Shakespeare play, said it was devastated to learn of his death.
In a statement Lyric’s executive producer Jimmy Fay paid tribute to Campbell, saying: “These islands have lost a great artist, and the sky is brighter tonight with his star.”
He said Campbell, who was from Belfast, had been part of the Lyric family for many years.
“Mick showed great strength and dignity in light of his diagnosis MND,” Fay said.
“He remained resilient and focused, creating dynamic work throughout his struggles.
“We at the Lyric pay tribute to his remarkable talent and send our deepest condolences to his wife Naomi, his mother and sisters, and all his friends, family and colleagues at this sad time.”
