“How’s Adam?” aside, EastEnders has a fairly good reputation for keeping blunders to a minimum.
However, bosses have let one slip through the net – and it hasn’t gone unnoticed by eagle-eyed fans.
In a blink-and-you’ll-miss-it moment from last Friday’s episode, a piece of rogue scenery with a warning message to crew members could be seen on camera in Dot Branning’s living room.
It was visible as character Sonia Fowler made her way to open the front door to police officers.
The message that read “DO NOT SET AND STRIKE” was also clearly in view.
However, as Sonia later returned to the living room, the scenery had mysteriously disappeared.
Of course, it still has nothing on the most famous EastEnders fail ever, which came courtesy of Jo Joyner during the live episode back in 2014.
The actor, who played Tanya Branning, made a huge gaffe when she referred to the character Ian Beale by his real name (Adam Woodyatt) during a scene with his on-screen wife.
