It is being filmmed in HERTFORD, BALLS PARK. They leave today so you have to go now rlleay. I tryed to go yesterday by saying I was going to ADVENTURE CASTLE (an indoor play area for kids) but because my friends and I were 17, as you can imagine he didnt believe us but he did let us go through. We didnt see robert Pattinson though, I think he was in a trailer. However we did see the trailers (which were very cool), cameras, camera men, the lights, makeup artists, hair stylists and body guards ect Just a shame we didnt see Robert rlleay. It is definitely a trip worth doing.
