Wow, what a compelling and dramatic performance by Jonah Hill ....and of course Joaquin Phoenix. I come to expect great and unique performances in everything that Joaquin does and am never disappointed, but what really stood out to me in this film was the performance of Jonah Hill. From what the announcer at Sundance 2018 described as a "chameleon like character", Jonah really drives it home with his portrayal as Donnie, the AA friend and sponsor to Joaquin's true life character John Callahan.
Much like the comics that John Callahan has made over the years, this movie is filled with a lot of humor, despite the struggles he faced throughout his life, including his addiction to alcohol. Donnie is there as a source of inspiration and guidance to John in helping him overcome these obstacles while also providing some comic relief. Jonah's performance really gives depth and insight to Joaquin's character as he struggles to pick up the pieces of his shattered life and continues on his journey to make some of the most outlandish and though provoking comics of his time.
Overall, I highly recommend watching this, as I feel we can all relate the context on some level. It will be quite the tear jerker towards the end and also allow you to empathize with both Donnie and John as they help each other overcome life's many hardships.
