“TODAY’S CONFIRMED LIST OF CHARACTERS AND ACTORS:
Rebolt – played by Ian Kenny
Moloch – played by Harley Durst
Moloch’s Henchman – played by Tien Hoang
We have also heard about “Gremm” and “Emlys Nest” in relation to these characters. We aren’t sure if they’re planets, places, or characters. It could really go either way. It almost sounds like a planet and a location to me but that’s just a wild guess.
Ian Kenny was first rumored by Variety back in March. The actor is primary known for the movie Sing Street where he plays a bully-turned-roadie for a high school rock band. (I recommend the film if you haven’t seen it–it’s on Netflix.) Harley Durst appears to mainly be a stunt performer known for the X-Men films. Tien Hoang seems pretty new to performing with his credits starting in 2015.”
