Just watched the Truman Show for the first time in years...

This was one of my favorite movies growing up and I found it for cheap on blu ray a few days ago. I was absolutely blown away by Jim Carrey's performance.

I've thought for years that eternal sunshine was probably Carrey's best movie (and it is damn good) but this just held up incredibly to my memory of what it was.

This was the first movie to make me cry since probably 50/50 and the moment near the end when Truman has survived the storm and starts to pull up the mast was one of the most genuine hero shots I've ever seen in a movie.

Can anyone here recommend other movies about pure perseverance that don't come off as over sappy or too bleak by the end? Preferably something close to the tone in the Truman Show.
