I watched Val tonight. Its mostly old footage that Val filmed himself. He was quick to have a video camera and seemed to carry it with him everywhere.
If you're unaware, Val Kilmer lost his voice during his treatment for throat cancer. He can still speak, but with difficulty.
Anyway, even if you're a mild fan of Kilmer's work, this is worth a watch. I much prefer this format for documentaries to the talking heads we get with other documentaries like Velvet Underground (2021)
Val is from Amazon Studios and A24.
