Muse (2019)

Luca is the pre-eminent artist of his generation and at the peak of his career, lauded, feted and collected by all. He is the ultimate showman however, his fortune and fame have left him agoraphobic and crippled by depression. He hasn't left his house in five years, he's a virtual recluse who battles daily with his demon. When a chance encounter brings Luca back from the edge, the question is, can he stay there.
