EastEnders legend Pam St Clement is swapping Albert Square for Casualty as she joins the medical drama for its 30th anniversary episode.
The actress, much-loved for playing Pat Butcher in EastEnders, will play grumpy patient Sally Hodge in Casualty's film-length anniversary show.
Sally is set to make life hell for nurse Charlie Fairhead (Derek Thompson).
Speaking to The Mirror, St Clement joked: "Put it this way, if Sally was walking down the same street as Pat Butcher, Pat would neatly sidestep on to the opposite pavement.
"She’s an unfortunate woman because of her emotional baggage and she doesn’t always come over as being very nice. But it was a nice complicated character to play – very condensed."
She added: "The episode is mostly about the regular cast and the amazing things that are done within Casualty, but it was a privilege to play a guest role within this incredible episode for the 30th anniversary.
"Most of the scenes I had were with Derek Thompson and with a bit of luck we absolutely clicked."
The actress's guest appearance airs on Saturday, August 27 on BBC One.
St Clement delighted soap fans when she made a surprise return to Albert Square recently when she appeared as a ghostly vision to a dying Peggy Mitchell (Barbara Windsor).
