I can't narrow it down to just 5 either so...
(all time fave, star studded cast and so many quotable lines!)The Pink Panther series
(sense a theme here?)Princess Bride The Great Race The Court Jester Young Frankenstein The Wizard of Oz Singing In The Rain Rear Window Vertigo Patton High Anxiety Double Indemnity Without A Clue Clue Raiders of the Lost Ark The Out-of-Towners The In-Laws (Serpentine! Serpentine! LOL) Too Many Disney Movies to name, so I'll just say Fantasia, Toy Story, and Lion King. The Blues Brothers Ghostbusters Best In Show Waiting For Guffman I re-read this whole thread and Jamanda's pick of End of the Spear... amazing movie. Not one of my faves, but it was a great and moving story. I remember reading a book about this true story, Beyond the Gates of Splendor, many many years ago.
