Director Bryan Singer has announced on Twitter that French actor Omar Sy has joined the cast of X-Men: Days of Future Past.

The 35-year-old (above) is known for his role in The Intouchables, released in the UK in September 2012.

Omar's character in the film has not been revealed, leaving many fans to speculate he could play Bishop, a mutant law enforcer from the dystopian future.

Although Bishop did not appear in the Days of Future Past comic book story, he was in the animated adaptation. But there's no official confirmation.

In other gossip, the blog Shadow and Act is reporting that Halle Berry hinted she's likely to be back as Storm.

The site said: "She did confirm to me that she would be returning in the role. Most likely. Practically 90 per cent sure.

"She told me that are a few details that are still being negotiated which she couldn't get into. But since she did tell me that the film starts shooting in April, it's highly unlikely that talks are going to fall apart and the producers have to find a replacement at the last minute."

In addition, Jennifer Lawrence - who is returning as the young Mystique (above right) - has spoken of her delight at not having to be covered in the blue paint that caused her skin problems in X-Men: First Class.

She told E!: "I'm so excited because I'm going to wear a body suit. It will be from neck down so it will cut out time and the blisters."

Continuing the unveiling of promotional material for Iron Man 3, Marvel Studios has delivered posters featuring Robert Downey Jr's Tony Stark/Iron Man, Ben Kingsley's Mandarin and Gwyneth Paltrow's Pepper Potts.

There are no real surprises, as we've seen images of these three before - including a reveal of the Mandarin - though you may notice Kingsley's character's attire is a rather curious combination of regal robes and camouflage combat fatigues.

All three images are featured here: one above, the others below. Iron Man 3 is out in the UK on April 26 and in the USA on May 3.

There's movement on Twentieth Century Fox's Fantastic Four reboot, with The Hollywood Reporter discovering that Seth Grahame-Smith has done some work on Jeremy Slater's screenplay.

Seth wrote the best-selling novels Pride & Prejudice & Zombies and Abraham Lincoln: Vampire Hunter, the latter adapted by Fox into a movie. He also scripted Tim Burton's Dark Shadows starring Johnny Depp.

Grahame-Smith (right) showed his interest in superheroes when, in 2006, he published The Spider-Man Handbook: The Ultimate Training Manual, a look at the Marvel Comics web-spinning hero, with an introduction by Stan Lee.

Sources have said that the new Fantastic Four reboot is "taking a grounded superhero and sci-fi approach to the heroes and will tap deep into the comics mythology, which featured not just the better-known villains such as Doctor Doom and Galactus but also alien races the Kree and the Skrull, and the anti-matter universe known as the Negative Zone."

And in what could be taken as a further indication of Fox's intention to have the film in the same universe as its other comic book-based franchise, X-Men: First Class director Matthew Vaughn recently came on board as a producer. Chronicle director Josh Trank is helming the project.

Next up from the studio in the superhero genre is The Wolverine, released this July, and then X-Men: Days of Future Past, which begins shooting in April.

With James McAvoy and Patrick Stewart playing the young and old Xavier, and Michael Fassbender and Ian McKellen as the two versions of Magneto, fans are wondering how the time-travel tale will all come together, and if these different incarnations will meet.

But McAvoy (right) appeared to rule out sharing screentime with Stewart. "It'll be cool, but I don't think we get any scenes together, sadly," he told Empire. "I don't think there's any future self talking to past self."

That's led to fans speculating that the time-spanning element of this adaptation of the classic comic book story could be the older Xavier's consciousness going back in time to possess his younger counterpart.

Director Bryan Singer had earlier told IGN: "The movie takes place at different times. It deals with, I don't want to say time travel, but time displacement. A form of time travel which is steeped more in the X-Men [mythos]."

X-Men: Days of Future Past is set for release in July 2014.
