Some major Summer blockbusters have been adding new faces to their cast over the course of the past week.

Though the casting of Chris Evans in the role of Steve Rogers in Joe Johnston‘s The First Avenger: Captain America and the news that Joss Whedon would be directing The Avengers has without doubt stolen the spotlight, there was still work to be done.

Hayley Atwell, who has starred in films like The Duchess and the TV mini-series remake of The Prisoner, has now been cast as the Captain America female lead, Peggy Carter. Atwell will be playing the the love interest of Rogers, and her character could become much larger depending upon how they take her comic book storyline and transfer it to the screen. Many actresses were looked at for this role, including Keira Knightley and Emily Blunt.

Many names were reportedly in consideration for the role of Captain America in The First Avenger: Captain America. We were told of quite a few of them toward the end of February (Read: Want To Know Who’s In The Running To Become Captain America?), but ironically, it’s now two candidates that were not part of that list who have won the lead roles.

It’s being reported that Sebastian Stan, who was at one time a possible choice to become the Captain himself, has been cast in the role of Bucky Barnes. He joins Chris Evans, who of course was recently offered and accepted the job to play the highly coveted superhero role.

Dark Castle Entertainment is known for their many contributions to the horror genre. One of their upcoming titles is The Apparition. The movie is adding a new name to the cast which now creates an interesting fusion of different juggernaut franchises.

ShockTilYouDrop is reporting that Tom Felton, who is best known as Draco Malfoy in the Harry Potter franchise, has been cast in the movie. Felton joins The Twilight Saga star Ashley Greene, creating said fusion. It’s always fun when the stars of two major franchises show up together in a completely different franchise, so all of the Potter-heads and Twi-hards will surely go nutty for this. Then again, sometimes these fusions are pretty anti-climactic, like when Firefly‘s Nathan Fillion teamed up with Battlestar Galactica‘s Katee Sackhoff for White Noise 2. Shame.

Not a whole lot is known about the movie, but it will delve into the realms of the supernatural when some sort of college experiment doesn’t go quite as planned.
