A few weeks ago, it was reported that the Osterley Park House would be used as Wayne Manor in The Dark Knight Rises. Many rooms of the house will be closed to the public later this month, to accommodate interior shoots for The Dark Knight Rises. Now, thanks to iTV Central, we know of another mansion that Christopher Nolan will be using as Wayne Manor. According to My Nottingham, Wollaton Hall and Park will be closed to the public from June 20th until July 6th, in order to enable “a film to have exclusive access to the site for filming”. Wollaton Hall looks very similar to Mentmore Towers, which was used as Wayne Manor in Batman Begins. I’m sure with a bit of Hollywood magic, Wollaton Hall will look just like Wayne Manor from Batman Begins… brick-for-brick.
Update: cwilliamson32 points out in the comments that Mentmore Towers was designed off Wollaton Hall, which is why the two buildings look so similar.
