It's been almost five years since my documentary Heart Attack! played the London Underground Film Festival. The event was at a venue called The Horse Hospital.
I didn't go to the screening, but I've been intrigued by this space. The description from the About Page from The Horse Hospital website is: Providing space for underground and avantgarde media since 1993.
And from their Homepage: Built in 1797 as stabling for cabby’s sick horses, The Horse Hospital is now a unique Grade II listed arts venue situated in an unspoilt mews in the heart of Bloomsbury.
Check out their website. And if you're in London, check out one of their events. If I ever go to London, The Horse Hospital will be at the top of my Must-See list.
