Now a luxury hotel,this is the space where "The Rocky Horror Picture Show" was filmed. Unless there’s a special event like the annual Time Warp Picnic, Oakley Court runs like any kind hotel, and but the patient staff is not phased by fans who pop in for the day and ask questions approximately film locations. You can easily spot the notorious staircase,entryway, Riff Raff's window, or the room where the dinner scene was filmed. There's even a grandfather clock in the lobby,although not the original. Oakley Court is conveniently located 20 minutes from Heathrow Airport on the River Thames. The 33-acre estate has the Downton Abbey vibe of an old English manor, which it once was.
