We were thinking of hiring from Seventh Art their film about the David Hockney exhibitions at the RA. But I've just heard from them that, as of a few days ago, you can see it for free on the RA website. We're thinking about hiring a different film. Meanwhile, do have a look at the Hockney film (80 mins, so settle in) at https://www.royalacademy.org.uk/article/exhibition-on-screen-documentary-david-hockney
The RA website also has several other videos,including a 40 min video tour of their excellent Picasso and Paper exhibition at https://www.royalacademy.org.uk/article/picasso-and-paper-virtual-exhibition-tour
Thank you for the information. We are going to hire a film too, and are thinking of the Van Gogh film as an initial trial to see how the take up from our members goes. Good luck with yours
