It was inevitable, as it was set up as a franchise from the get-go. Today, Conan the Barbarian star Jason Momoa has confirmed that Conan the Barbarian 2 is in development. He also says he's seen the first film, and that its (of course) fantastic.
When asked if he would play Conan again, this is what Jason Momoa had to say.
"Oh, yeah. There are sequels to everything. There's a Fast & Furious seven, isn't there? There's like four Pirates of the Caribbean. I got to see a rough cut, and people are going to be stoked. We're not remaking anything Arnold Schwarzenegger did. It's a totally new story. The same legendary character. We're taking these tons and tons of great Robert E. Howard stories from the 30s, and combining a couple and bringing it to audiences in a way that's new and fresh."
There is no set start date for Conan the Barbarian 2 at this time.
