Jason Momoa was in the running for Drax but he turned it down. He told IGN, “I want my children to see their father happy. It’s not that it’s not a good role, it just wasn’t the right thing. I was on Stargate: Atlantis for four years playing a similar character called Ronon, who was an alien who didn’t say much and grunted. I’ve been there and done that, whether people have seen it or not.”
