The 42-year-old actor shared his plan to keep season three spoilers at bay in an interview with Time Out on Wednesday, revealing that this time around, it's going to be a bit harder to get secrets out of him.
"It’s so funny, I get in so much trouble revealing little things, so my mouth has been completely shut any time someone asks," he joked. "I will tell you this: I haven’t read the scripts yet, but from what [I've heard so far] it sounds really, really fun and really amazing. I’m constantly surprised by these writers."
Harbour had no problem gushing about his younger co-stars, however.
"You’re dealing with hormonal teenage boys. I think it’s the most difficult time in a person’s life, because your body is going through changes and you can’t keep up, so there would be days when they would lose control of their bodies," he said. "We would be doing a take and then one of them would just fart and ruin the take."
"They are amazing in the opposite way, too," he continued. "Whenever we have a good scene, we all huddle around and they all want to hug each other and then I’ll get involved in that too and it sort of warms my cold, dead heart to have a co-star come over and say, 'That was a great scene, come give me a hug!' It’s a very unique, singular experience to be working with these kids!"
While Harbour waits to start filming season three, he's checking a few things off his bucket list -- like dancing with penguins. The actor reached out to Greenpeace via Twitter a few weeks ago, asking how many retweets he needed before they would send him to Antarctica to meet some emperor penguins. They replied 200,000 -- and he got 387,000.
"It’s a really interesting frontier that we’re still exploring, and my relationship to it has gone through many different stages," he said of the power of social media. "I think silliness is kind of important in the interaction, and I also think what’s important is that people don’t feel manipulated, that they just feel like you’re not trying to sell them something, you’re not trying to do something to make yourself feel better about yourself or something like that.
"I think it’s a way to have fun, it’s a way to contribute to the world, it’s a way to make people feel good -- which is ultimately what I want. I want human beings to feel happier and more empathetic and I want us all to come together in a global community and just set down these weapons and say, 'Hey, [we’re all] human beings and we can still get along and have some fun,'" added Harbour, who posed in a fan's senior portraits and will officiate another's wedding thanks to Twitter. "It’s a very naive take but I think [the platform] allows me to have some of that naiveté [as it allowed me to] go dance with penguins!"
