When everyday life gets you down, nothing can turn your mood around like a great comedy movie, so use this list to head out to the video store (or onto Netflix) and watch one of the best comedy movies of all time. Comedy movies are made to make you laugh, but the best ones can also make you cry or make you think. While this list of the best comedy movies draws entries from across the 20th century, you will see that comedies had their heyday in the 1970's and 1980's.

  1. "Monty Python and the Holy Grail." Monty Python had a couple of great films, but none were quite as majestic or as hilarious as "Monty Python and the Holy Grail." The movie follows King Arthur as he collects his knights and heads out in search of the grail. No other movie in history (outside of maybe Casablanca) has given us more quotable moments, from "Just a flesh wound" to "Your mother is a hamster and your father smells of elderberries."

  2. "Blazing Saddles." Mel Brooks has made a number of amazing films over the years, but "Blazing Saddles" stand above everything else because of how funny it is despite discussing some very serious topics. When a racist town in the west gets saddled with a black sheriff so the people will be forced out and the land will become cheap, all sorts of hilarity ensues.

  3. "Ghostbusters." A couple of comedy heavyweights got together to make this one unforgettable movie. New York starts to get overrun with ghosts, and only a handful of misfit paranormal investigators can save the day. The movie culminates when Zuul takes the form of a building-sized Stay Puft Marshmellow Man.

  4. "Shaun of the Dead." This film came out of nowhere and is just absolute perfection. It follows a young British loser as he is a little slow to realize that zombies are taking over the city. As the film progresses, it amazingly transfers into almost a complete action/horror film. The writing and acting make "Shaun of the Dead" one of the best comedy movies of all time.

  5. "This is Spinal Tap." This is the ultimate movie mockumentary, filled with some of the most classic lines in movie comedy history. The film follows a made-up rock band as they go on tour and get into all kinds of trouble.

  6. "Airplane!." "Airplane!" is a satirical look at the movie "Zero Hour," as well as a bunch of other movies with similar plots. The film is pure slapsitck, with a bunch of quick, funny jokes loosely based around the overall plot of a distressed airplane.

  7. "Clerks." Kevin Smith burst onto the movie scene with this low-budget look at real everyday life in New Jersey. Sure the plot may be a little out there, but the characters are grounded in reality and the dialog is second-to-none.

  8. "Duck Soup." The Marx brothers made a number of films, but only "Duck Soup" is remembered as one of the greatest comedy movies of all time. The movie is a farcical look at two fictional countries led by some very interesting people.

  9. "Planes, Trains and Automobiles." Not only do John Candy and Steve Martin make this one of the funniest movies in history, but the end of the film also makes this one of the most touching. Two people who couldn't be more different have to work together to get home, but some surprising secrets make this so much more than just a cross-country trip.

  10. "Beverly Hills Cop." While Eddie Murphy makes this one of the best comedies ever, the film also includes a hefty amount of action. A Detriot detective heads to Beverly Hills when he traces his friend's murderer there. This movie is a very interesting look at a fish-out-of-water story.
