The studios have a complex history: Elstree Studios is a generic term which can refer to several current and defunct British film studios and television studios based in or around the towns of Borehamwood and Elstree in Hertfordshire. Studios have been located there since film production began in the area during 1914. Wikipedia gives 7 separate addresses.
The studios produce films and television programmes. Many major films have been all or partly made here, including 'The Shining' and the 'Star Wars' and 'Indiana Jones' series. Television productions include 'Big Brother', 'Strictly Come Dancing' and 'Dancing on Ice'.
2021: Paul Welsh MBE, historian of Elstree Studios, wrote a piece about the BFI plaques erected by Elstree Studio for This Is Local London : about 25 years ago "the British Film Institute decided that 200 film plaques should be erected around the UK and they would be free, so I applied and received 20. This was in recognition of the unique film history of Elstree and Borehamwood."
