Apparently the stuff from Crimson Peak looks really cool. Imagine the "pale man" from Pan's Labyrinth only red. The creatures also look cool, some have portions of their head missing (yay for Boneyard F/X). From what I gathered, your excitement should be high for this maze.
In regards to "This is the End's" façade being James Franco's house, it can be done easily. You don't need anything big/fancy to pull that off, especially due to the limited space.... you mainly just the front door section. You remember the big southern mansion in TCM? Well, at HHN Orlando in 2007 we had that house in the Disaster (Earthquake) queue which has a roof for those not familiar with the location. While we've seen much larger, grander more elaborate facades over the past few years... this is what they did for TCM
So having Franco's house as the façade is very believable.
