Of course we have my original choices.
Jared Padalicki - Nova/Richard Rider
He's a really good actor and looks a hell of a lot like Nova.
Jensen Ackles - Quasar/Wendell Vaughn
Though I haven't seen Supernatural, only clips of it, Jensen Ackles and Jared Padalicki seems to have great chemistry on screen and I could believe them to be really good friends like Nova and Quasar.
Sean Maher - Adam Warlock/Magus
You might disagree with me on this one but I think Sean Maher would make brilliant Adam Warlock. I know I've kinda made this into a Firefly reunion with Nathan and Adam as well, but I think Sean would do a great job with Adam Warlock.
Alexa Havins - Phyla-Vell/Martyr
A fantastic actress! I loved her in Torchwood: Miracle Day and I think if you cut her hair short, we would have the perfect Phyla-Vell.
Dichen Lachman - Mantis
To be honest with you, I had a pretty hard time finding an actress for Mantis, but I think Dichen Lachman would do a brilliant job a portraying her.
Doug Jones - Bug
He is perfect for Bug! I don't really need to explain why, if you know what Doug Jones is capable of, He would be prefect!
Garrett Hedlund - Jack Flag/Jack Harrison
I think Garrett Hedlund is a pretty good actor, He was the one I was thinking of when I was thinking of Jack Flag.
Angelina Jolie - Moondragon
I think Angelina Jolie is prefect for Moondragon! She has the look and mostly importantly she has the acting chops.
Brad Pitt - Major Victory/Vance Astro
Brad Pitt is a fantastic actor, he would kick ass as Major Victory!
Corey Burton - Worldmind
I always imagined Worldmind having a Brainiac-esque voice, so I went with the voice of Brainiac himself.
Damion Poitier - Thanos
Keeping the continuity with the MCU and I think he looks a lot like Thanos.
