Oh, so the studio 13 haunted house is going to have characters from horror movies. At first I was thinking that it was just supposed to be a haunted backlot with zombie directors and producers which would have been kind of weird. Maybe it'll actually be scarier this year.
No, i'm pretty sure hes right. JPM is for street and haunted house actors only. Six Flags does all of the shows themselves. LAFF, that gipsie lady, Manny B, the pumpkin guy, and all the others. I'm pretty sure the train ride is considered a show. The only exception being last year because the actors were scaring. So it may be up to SF every year wether they do it or if JPM does it.
Last year the train was staffed by our entertainment department, if I remember correctly, which was shorthanded. It had to close several times to allow all the actors to take breaks together. I do recall the Scooby Doo showing up on the JPM list but I think it was a mix of our actors/actresses and JPM people.
The Scooby show was entirely staffed by JPM, Hold-up Express was staffed by SFGAm's Entertainment department. IF and I stress the IF there's a train show this year it will be staffed by SFGAm's Entertainment department...but sadly it wouldn't surprise me at all if there were no train show this year.
