Mark LaMura, best known for playing Mark Dalton on the long-running ABC soap opera "All My Children," has died at the age of 68.
LaMura passed away on Sept. 11 after a struggle with lung cancer, Deadline reports. His death was confirmed by former "All My Children" co-star Susan Lucci.
"How can this be? I just received the shocking and deeply saddening news that wonderful Mark LaMura has passed away," Lucci wrote on Instagram.
"Mark played my brother Mark on All My Children -- he was such a talented and accomplished actor/ a bright and charming presence in all our AMC lives -- and a really great guy. Mark was loved and he will be missed! RIP, my friend."
LaMura was a regular on "All My Children" from 1977 to 1989 and made guest appearances throughout the '90s. Some of his character's more memorable subplots included romantically pursuing his sister before he knew she was his sister, being the subject of an intervention for his drug addiction and later returning to help his sister overcome her alcoholism, according to TV Line.
He was nominated for a Daytime Emmy in 1988.
LaMura's other television credits include "Star Trek: The Next Generation," "L.A. Law," "The Sopranos," "One Life to Live," "Law & Order: SVU," "30 Rock" and "Damages," according to People.
In 2012, LaMura gave an interview to We Love Soaps in which he recalled the downsides of acting in soap operas like "All My Children."
"It took the work of thousands of actors, writers, producers, lighting men, camera people, an army of artists and workers, to get one hour's worth of story every day," he said. "The problem with them is they cost too much compared to four hosts and a guest sitting on a couch. To act in them, however, was like being able to play all 88 keys on a piano and only being allowed to plunk out the same 8 every day."
"To be fair, the writers have to write an hour's worth of story every day," he continued. "The director has to shoot it, the actors have to learn 'all them words' the night before. Love -- no. Thanks for the dough. It was a heavy like affair."
ABC cancelled "All My Children" in 2011. It was briefly revived as a web series by Prospect Park before being cancelled again in 2013 due to low ratings, a lack of funding and a protracted legal battle with ABC over rights, according to the Los Angeles Times.
