Hit Fix rings us the following casting news:
By far, though, the biggest news that's brewing about "Guardians" right now involves a character named Rhomann Dey. They've made an offer to John C. Reilly to play the part, and if he comes aboard, it's a big commitment. Basically, he's been designed as the Agent Coulson of the "Guardians" movies. He's the human agent who serves as a go-between, keeping the Guardians in line and reporting to SHIELD about their activities.
What's that you say? Rhomann Dey was the leader of the Nova Corps in the comics and not a human being on Earth? And he basically became the Abin Sur of the Marvel Universe when he picked Richard Rider to give his Nova powers to?
Hmmmmm. Very, very interesting.
There's a hint that we'll see some other familiar faces. Groot, for example, originally comes to Earth looking to experiment on humans, but Nick Fury talks him out of his and convinces him to help us instead. But Dey is going to be the primary face of normal humanity for the "Guardians" films, and Reilly would be an intriguing addition to the Marvel Universe. He's got the exact right demeanor for a movie featuring talking trees, weapon-bearing raccoons and walruses, and lots of drop-ins from outer space. He'll have a peer, someone who is their liaison for the Guardians, and Marvel is looking at names as disparate as Hugh Laurie, Alan Rickman, and Ken Watanabe for that part.
