Casualty actor Charles Venn has said fans are in for a big treat as part of celebrations for the medical drama's 30th anniversary.
An adrenalin-charged 110-minute special episode will be broadcast on BBC One at the end of the current series.
The former EastEnders star, who plays nurse Jacob Masters, told What's On TV magazine that his character will play a key role in the forthcoming instalment.
"I don't want to give anything away, but my character Jacob is an integral part of it," he said. "It's action-packed and I get to do a few stunts, which is a dream come true for me. I wanted to be a stuntman when I was younger. The 110-minute 30th anniversary episode is like a film and we call it Casualty: The Movie."
Charles played Albert Square's Ray Dixon, a boyfriend of Bianca Butcher (Patsy Palmer) and the father of her young son Morgan. He joined Casualty in 2015.
The long-running series is pulling out all the stops to mark its milestone anniversary. It has already been announced that the 1000th episode features a special cameo appearance from the much-loved Lisa 'Duffy' Duffin, played by Cathy Shipton, on June 26.
Duffy will also return to the show permanently in August to reunite with the Holby Emergency Department team.
London-born Cathy was an original cast member of Casualty when it launched in 1986.
Talking about her forthcoming comeback, she said: "After returning last year for episodes one and two of series 30, many asked if Duffy was sticking around long-term. Well, the response was so positive that I've stepped right through and am thrilled to be back on the show.
"The future looks very exciting for Duffy both professionally and personally, and I am equally excited to be working with such a talented and creative team of actors, writers, directors and producers."
Casualty fans can expect more surprises as the show celebrates a momentous achievement.
