I'm surprised that nobody has mentioned Forest Gump by Winston Groom yet. I'm not sure if his low intelligence counts as a disability, but he never let it get in the way of his life. Lieutenant Dan, another character in the book, is definitely disabled after the Vietnam War, but his life changes thanks to Forest. In any case, I mostly read young adult books, so my recommendations would be Five Flavors of Dumb by Anthony John, Loving April by Melvin Burgess and Read My Lips by Teri Brown. These books all feature protagonists who all have some type of hearing disability.

Wasn't Franz Kafka busy with more than one book before he died?

I have found that it is actually musicians who tend to have the most interesting biographies and I can name plenty of great ones, but your question is specifically about actors and actresses so I'll stick to that. Maybe I should post my own question about musician biographies :)

Robin by Dave Itzkoff - Everyone remembers Robin Williams as the funny guy who was always cracking jokes and making people laugh. I think very few people ever knew what went on behind the scenes in his life and how much he struggled with self-doubt. There are a lot of information in this biography that I never even knew about and I'm a big fan of Robin Williams. His death came as a huge shock to the world, but after reading this biography and finding out about his addiction and depression I can understand why he did what he did.

Wishful Drinking by Carrie Fisher - This is another great biography by an actress that is sadly no longer with us. Everyone who only knows Carrie Fisher as the beautiful Princess Leia from the Star Wars movies are in for a bit of a shock if they read this biography. Carrie was undeniably a brilliant and talented actress but she also had her struggles with addiction and suffered from manic depression. I never would have thought that Princess Leia spent time at a fair amount of mental institutions either. This is not just a biography for Star Wars fans, but for anyone who can appreciate well written true life stories.

I Can't Make This Up by Keven Hart - Kevin Hart is another comedian who hides a lot of hardship behind his smile. The odds were overwhelmingly against him ever becoming a success as he grew up in a household where his father was a drug addict while his brother was a drug dealer. Yet, somehow, Kevin managed to not follow in their footsteps and instead pursued his dreams to get him to where he is today.

Troublemaker: Surviving Hollywood and Scientology by Leah Remini - I fell in love with Leah Remini watching the show The King of Queens, but I never had any idea that she was a former Scientologist until I saw her biography. Imagine my surprise when it turns out that she was raised as a member of the church and was part of it up until 2013 when she left. Since then she has been a constant thorn in their side and followed up her biography with a series as well.

Christopher Johnson McCandless. He is the protagonist of Into the Wild from Jon Krakauer and I've honestly never been more frustrated with any character ever. I get that McCandless was a real person who really young due to no doubt the stupid decisions that he made, but reading how it all happened is jsut so frustrating. He appears to have been one of those people who just was not capable of making good decisions even when given sound advice and that is endlessly frustrating to someone like me. It's really tragic how it all played out, but I can honestly say I was not surprised that "Supertramp" didn't make it.

In my opinion, the movie of Fahrenheit 451 was much better than the book; the characterisation and plot was more believable. To expand further would spoil the book for anyone wanting to read it.

Also, the Truman Capote novella Breakfast At Tiffany's is very much darker and, to me, less satisfying that the amazing movie. It's almost an entirely different story told from the point of view of Holly's neighbour. The ending was drastically changed for the film, for the better, in my view.
