1 - Good Will Hunting

This is an easy choice for me.  Not only do I think this is Williams' best performance, but it's one of my favorite films as well.  Even in some of Williams' more serious roles like Good Morning, Vietnam, he was still "Robin". There's none of that here as therapist Sean Maquire.  Sean doesn't just unlock Will's potential as a genius, he makes him a better person.  Williams gives a powerful, heartwarming performance.  There are so many great scenes in this film that I lost count, but what is most amazing about Williams' performance is that there is no shred of his normal Robin Williams shtick in Sean Maquire.  It's just Robin losing himself in the character of his career.

2 - Dead Poets Society

Oddly enough, there are two films on my list that we actually watched in school.  First is Dead Poets Society, which I watched as part of my high school English class.  Dead Poets Society is one of the earliest films that showed off Williams' range as a dramatic actor.  Going to an all boys catholic school, it was easy for me to see similarities to the boys in the film as well as Williams' inspiring English teacher John Keating.  Of all his roles, this might be the one that stands out for most people.  A generation of students were introduced to Robin Williams after watching Dead Poets Society and generations to come will do the same.

3 - Good Morning, Vietnam

Some consider Good Morning, Vietnam as the first dramatic role in Williams' career.  It turns out that it was the perfect role for him.  As the wacky DJ at the US Armed Forces Radio station in Vietnam, Williams was able to bring his patented brand of comedy to the role.  A stream of conscious, rapid fire smorgasbord of crazy voices and characters desperate to bring even a sliver of happiness to the battered and beaten American troops.  Even for those who haven't seen the film, almost everybody has heard Williams' voice bellowing the title of the film: "GOOOOOOOOOOOOOD MOOOOOOOOOORNING, VIETNAAAAAAAAAAAAM!"

4 - Aladdin

Millions of children across the world were introduced to Robin Williams without even realizing it as the hip, unfiltered Genie. Once again, Williams' role in Aladdin was a match made in Heaven.  Much of Williams' performance was actually ad-libbed, something he would become known for in many of his roles. Almost every animated film today tries to duplicate the successful formula of the colorful sidekick.  Most don't even come close to this classic Disney film.

5 - Mrs. Doubtfire

Over the years, Mrs. Doubtfire has been brushed off as the "movie where Robin Williams dresses up as a woman."  In reality, Mrs. Doubtfire is so much more than that.  It's a film about divorce and family.  The film includes more than a few tear inducing moments.  Along with Aladdin, Mrs. Doubtfire is another film that endeared Williams to a generation of children.

6 - Patch Adams

I remember seeing Patch Adams in the theater when it was released and really enjoying it.  It wasn't until years later when I started getting more and more serious into film that I realized how poorly it was received.  I guess many critics slammed the film for being too cheesy and overly sentimental.  Admittedly, I haven't seen the film since it was released in 1998.  I've seen thousands of films since then and have become more cultured in the world of cinema, because of this I don't plan on ever watching Patch Adams again.  I feel I would watch the movie with this new information and it would now cloud my judgement on a film I once enjoyed. 

7 - Bicentemnial Man

Bicentennial Man is the second film I had to watch for school. Unlike Dead Poets Society that we actually watched in class, I had to watch Bicentennial Man on my own time for a college class I was taking.  I remember seeing the film with my sister in an empty theater in the middle of the week.  Like Patch Adams, Bicentennial Man wasn't well received either.  I love Sci-Fi films so I was intrigued by some of the themes Bicentennial Man explored.  It's safe to say that Bicentennial Man was one of WIliams' more subdued roles.  Regardless, it's a movie that has stuck with me for over 15 years.  I also thought it was really cool that I got to go to the movies as part of a school assignment.

8 - One Hour Photo

When people talk about Robin Williams films, they mostly talk about many of the films listed above.  Not to mention quite a few films that didn't make my list like Jumaniji, What Dreams May Come and Hook.  A movie they rarely talk about is One Hour Photo.  That's too bad because it's an interesting film that features a fantastic performance by Robin Williams. Williams once again shows off his range by playing a villain, which was a rare role for him.  He plays Seymour, a lonely lab technician at a one-hour photo center.  Seymour becomes obsessed with one of the families that frequently gets film developed.  Williams gives a sad, creepy performance, but he's so good that you can't help but feel bad for Seymour.  A lot of people might have missed this one, but I urge you now to give it a chance.

9 - Insomnia

I'm a huge fan of Christopher Nolan's films.  He's made some of the best films of the last 15 years.  I love Memento, the Batman trilogy, Inception and The Prestige.  The one film of his that I was somewhat indifferent on is Insomnia.  I didn't hate it, but I didn't love it either.  People have told me to go back and give it another chance and I might just do that. Although I didn't love the film, the main thing that stands out in my mind about Insomnia is Williams' performance.  Once again he's playing a villain.  This time it's a cold, calculating murderer being hunted down by a beleaguered Al Pacino.

10 - Popeye

Some people might role their eyes at the inclusion of Popeye on any list of Robin Williams' best films, but there's a reason my list wouldn't be complete without Popeye.  As a little kid, I was a huge fan of the Popeye cartoon.  Also, the Popeye video game on the ColecoVision is one of my earliest memories of playing video games.  I loved Popeye so much that I begged my Dad to buy me a can of Popeye spinach.  Much to my surprise, the spinach tasted horrible to my childish pallet and the worst shock yet was that it didn't make me spontaneously sprout massive muscles.  Anyway, before I even knew who Robin Williams was, I remember watching Popeye.  In fact, I can honestly say that the film Popeye is one of my earliest memories of watching a movie.  I must have been 4 or 5 when I saw the movie and I haven't seen it since.  All that remains are vague memories of a few scenes.  The fact that I've grown into such a huge fan of movies and yet images from Popeye are still with me today make it impossible for me to leave it off my list.
