The popular soap character can seen in the trailer brandishing a machine gun.
The first trailer for the Hellboy reboot has dropped and fans got a bit of a surprise when they spotted a familiar looking woman.
Within the opening seconds of the clip, actress Laila Morse appears.
The 73 year old is best known for playing Big Mo Harris in EastEnders, a character described as 'a female Del Boy', who has featured in the soap since 2000.
In the new Hellboy movie, Laila is working in a chipper in London and can be later seen firing a massive machine.
No, we're not joking! Have a look at the trailer below.
The upcoming superhero movie, based on the Dark Horse Comics character of the same name, stars Stranger Things actor David Harbour in the title role.
The reboot is said to stick closer to Mike Mignola's comic book series than the previous films.
But we're not too concerned about that - we're all about Big Mo.
And it seems fans are too.
Not here for #Hellboy so much as Big Mo running a chippy. pic.twitter.com/muVkv9j5xo
