Alexa Vega.
She's one of the most talented young actresses in Hollywood right now, IMO. I can't wait to see her performance in this.
I like the sound of the movie too. I love the fact that this movie is going to be in the vein of Goosebumps. Who doesn't love that show? Love the setting of a mine too - it was a great location used in My Bloody Valentine and its' remake.
Looking forward to seeing some footage.
