Gonna be a sequel not a remake
On the one hand i am glad the Rock isn't going to be playing Jack Burton.He would have been a terrible choice for that part.On the other hand i don't know if a sequel starring the Rock is any better.I like the Rock in general but i don't feel like he fits this franchise.
