Paul Giamatti

Paul Giamatti—man, where do we even start? This guy swings and misses in roles that you didn’t even know you wanted to see. It’s like he’s the human embodiment of that coffee shop where you never expected to find the best chai latte, yet here he is, serving up performances that are rich, complex, and a little bit weird. He’s the friend who always insists on showing you that obscure indie film you've never heard of but ends up blowing your mind. Seriously, how is he not the first name that pops up when you think 'underrated'? If you’re not talking about Giamatti, are you even having a real debate on the greatest actors? I mean, come on, let’s not sleep on this gem of a dude!
