New characters are set to join the 'Avengers'.
According to Badass Digest, the latest movie in the franchise 'Avengers: Age Of Ultron' will finish with Captain America creating a new team of superheroes by combining the existing characters with a host of new stars.
While full details of the new team are yet to be released it is reportedly set to feature a new heroine, Ms Marvel, also known as Captain Marvel, although movie bosses aren't sure whether this will be a lead or supporting role.
Meanwhile, Stellan Skarsgard recently confirmed he will star in the blockbuster.
The 63-year-old actor will reprise his role as Dr. Erik Selvig in the 'Avengers Assemble' sequel but admits he is only going to make a ''small appearance'' in the hotly anticipated superhero movie.
He said: ''I'm going to be in 'Avengers: Age of Ultron', a small appearance.
''I don't know what I'm allowed to say. But usually they call me in if they need something explained [to the audience].
''There's a lot of explanations to do when it comes to that universe.''
It didn't appear to take much to convince Stellan to return for the 'Avengers' sequel as he admits he loves working with the studio because there is a personal touch and he knows he can give producer Kevin Feige a ring if he has an issue with something.
He added to Total Film magazine: ''I like working with them because if I have a problem with the scene, I have Kevin Feige's number. I can call the head of the studio. You can't do that when you work on a normal Disney film or with Warner Bros. or Paramount.''
Stellan also played Erik is 2011's 'Thor' and the sequel 'Thor: The Dark World'.
'Avengers: Age of Ultron' has completed filming and will be released on May 1, 2015.
