McElhone will be playing the visionary British CEO of the company behind the mission to Mars if sources are correct. “I am so excited to work with original, maverick artists like Beau Willimon and Sean Penn — it’s a real privilege to be invited,” said McElhone. “As well as exploring Mars; I am thrilled to be accommodated by the brilliant planet Hulu and my favorite homegrown one of Channel 4.”
Sean Penn as Tom Haggerty looks up to the stars, or Mars, as he must be contemplating the great challenge before the team. Willimon said of Penn, “I have such deep admiration for Sean’s immense talent and extraordinary body of work. I feel very lucky to be collaborating with an artist of his caliber.”
Anna Jacoby-Heron is believed to be playing Sean Penn's daughter, as yet unnamed. As the series will be focusing not only on the astronauts, but also on their families and loved ones, as well as the ground team on Earth, it makes sense that we get to know at least one child of the main cast regularly.
Sean Penn plays former astronaut, Tom Haggerty. “I have such deep admiration for Sean’s immense talent and extraordinary body of work,” said Willimon. “I feel very lucky to be collaborating with an artist of his caliber.”
Natascha McElhone left Designated Survivor for this role on The First, from House of Cards creator, Beau Willimon. Considering what happened to Designated Survivor, it was a very good move on her part!
