We’re a good two years off before we see Marvel’s The Avengers 2, but we already know that Joss Whedon is working hard on the script and it’s been confirmed a week ago that the sister and brother team of Scarlet Witch and Quicksilver will be joining the cast as the big additions to the team this time around.

There are probably a lot of thoughts about who should be cast in these roles and how they should be portrayed, but we’ve learned that Marvel and Joss definitely have a few ideas already and one of them is that the duo are going to be younger than the rest of the team.

Although Joss is still writing and probably not ready to send anything out to actors, for the two roles, they’re generally looking for actors in their 20s and we’ve heard word that the “prototype” for their Scarlet Witch is none other than Irish actress Saoirse Ronan. Except something to note is that they’re going “British” for the role rather than trying to have actors playing Eastern Europeans.

As it happens, Ronan just turned 19 last month and she will be turning 20 sometime during the time they would be filming the movie next year though she’s also already been playing more mature roles. If she is Marvel’s “prototype” for Wanda, why wouldn’t Marvel just outright make an offer to Ronan once they have a script done? Ronan has those mesmerizing eyes that would be perfect for the Scarlet Witch, too.

As far as Wanda’s brother Pietro–now we’re assuming they’re going to use the same first names from the comics even though they’re played as British—he’s only described as being “euro” and “edgy,” but there are plenty of British actors in their 20s who could fit that bill. Come on SHH readers, what actor could hold their own against Ms. Ronan? Please don’t mention either of the actors from The Host, though.

While we know from talking to Kevin Feige about Marvel’s deal with Fox to use the character that there won’t be any mention of the brother and sister being mutants or who their father might be (Spoiler: He’s played by Ian McKellen in Bryan Singer’s upcoming X-Men movie!), the Scarlet Witch and Quicksilver are two classic Avengers who joined the team way back in Avengers #16, cover-dated May 1965, and the Witch has been a pivotal part of the team ever since. In fact, the Scarlet Witch is still a large part of the Avengers today having just been brought back into the fold with Rick Remender’s “The Uncanny Avengers” that kicked off the Marvel NOW! initiative.

There is a lot of history that she brings to the team, although we have a feeling that they’re going to follow the model of how the characters were used in Mark Millar and Bryan Hitch’s The Ultimates, which has been a fine blueprint for Marvel’s Cinematic Universe so far.
