The 42-year-old actor and Sudol boarded the Greenpeace ship in London to set sail for Antarctica. They will be helping in the gathering of scientific evidence with the Antarctic Ocean Sanctuary to safeguard penguins and whales.
Harbour had earlier tweeted to Greenpeace asking, "how many retweets to send me someplace to tell emperor penguin couples I think they have terrific parenting ideologies? Perhaps hone the Hopper dance with the males..."
"Hmm, if you get over 200k well ask the Captain if you can join our expedition to the Antarctic and dance with the penguins," Greenpeace had tweeted in response.
"Get your dancing shoes on, because youll be heading to Antarctica in no time," Greenpeace had written to Harbour.

Now, both Harbour and Sudol are heading to Antartica, and the actor, in a statement, said, "Well, Greenpeace says the Weddell Sea and its surroundings are home to a precious ecosystem, vital to sustaining our future. And that theres penguins there."
"And that I'll get to waddle around with them, discuss their parenting techniques with them and yes, yes, dance with them. And that they'll film it. And that if maybe I get enough support from everybody, they'll gimme that video, so I can rent it out to you (be kind, rewind please)."
The 'Protect the Antarctic' campaign is also supported by actors Gillian Anderson, Javier Bardem, Gwendoline Christie, Judi Dench, Ralph Fiennes, Vanessa Kirby, Joanna Lumley, Helen Mirren, Thandie Newton, Simon Pegg, Vanessa Redgrave, Mark Rylance, Alexander Skarsgard, and other prominent celebs from around the world.
