Avengers Endgame: Major spoilers leaked as FULL cast list is revealed ahead of release

WARNING: Mild spoilers ahead for Avengers: Endgame.

The film has already launched in some international territories, and will hit the UK tomorrow.

Its US release, meanwhile, is slated for Friday.

Express.co.uk won’t go into specifics until the film is out on our shores, but IMDb’s cast list tells you all you need to know about who’s back.

While some of the comebacks are expected, and have barely been kept secret by the stars who play them, there are some genuine surprises that will make fans gasp.

Reviews have made no secret of the fact that the Marvel movie pays excellent fan service – and some of these comebacks will be just what they want.

That being said, there are a couple of blink-and-you-miss-it cameos that aren’t even on the IMDb list at time of writing.

Suffice to say, fans will be more than impressed with the volume of talent in this film.

So will Natalie Portman be back, as rumoured? Is Hayley Atwell reprising the role of Peggy despite not claiming to know who Thanos is? What about Emily VanCamp’s Sharon? Or pre-snap fatalities like Tom Hiddleston’s Loki or Idris Elba’s Heimdall? We’re staying tight-lipped until the UK release, but we can tell you that this particular leak is false.

After that, no plans have been formally announced; although a prequel for Black Widow and an intro movie for Shang-Chi are both believed to be en route.

The Eternals – rumoured to star Angelina Jolie, and introduce the MCU’s first openly gay superhero – is also believed to be on the cards.

Black Panther, Doctor Strange and Captain Marvel should have sequels in the works too.

Avengers: Endgame is out tomorrow in the UK.
