EastEnders star Michael Greco has criticised Hollyoaks for casting brothers AJ and Curtis Pritchard.
The former Strictly Come Dancing professional dancer has played Marco on the show since March, and his younger sibling Curtis, who shot to fame on Love Island, made his debut as Jacob on the Channel 4 soap last week.
However, one of the duo's scenes, which features the brothers meeting in a children's playground and plotting the downfall of dance school teacher Trish Minniver, played by Denise Welch, has gone viral due to their performances.
The clip has been the subject of jokes and criticism on social media, and Michael, who starred as lothario Beppe di Marco on EastEnders between 1998 and 2002, took to Twitter to share his frustration.
"This is everything and more that is wrong with an industry I love. These people that suddenly come up with these casting ideas need to resign immediately. Shocking," he wrote in the now-deleted tirade.
He then later posted: "I think people can watch this and learn so much from it. How 'not' to act. Shocking."
Gerard McCarthy, who played Kris Fisher on Hollyoaks from 2006 to 2010, also shared the viral clip of AJ and Curtis' scene and didn't hold back when it came to his critique of the duo's acting abilities.
"The next time a producer/casting director says the words 'but they have a big social media following'.... Just point them in the direction of this absolute car crash!" he fired.
"It's a simple idea: stop giving actors' jobs to models / reality tv contestants / pop stars from 1995 / Crufts winners / anybody else who is not an actor. THEY WILL BE S**T!" Kris added.
