Dave's Movie Database, a site that combines as many sources as possible to get near definitive lists.

I've loved this site for a long time. He combines things like best-of lists, box-office, reviews & ratings, awards etc. to get as near a definitive list as possible. He also has similar sites for Music & BooksCurrently, according to the site, the Top 100 movies of all time are1: The Godfather (1972)2: Gone with the Wind (1939)3: Star Wars - Episode IV: A New Hope (1977)4: Citizen Kane (1941)5: Schindler's List (1993)6: Casablanca (1942)7: 2001: A Space Odyssey (1968)8: E.T. the Extra-Terrestrial (1982)9: Jaws (1975)10: Apocalypse Now (1979)11: Lawrence of Arabia (1962)12: Psycho (1960)13: Vertigo (1958)14: The Godfather Part II (1974)15: The Lord of the Rings: The Return of the King (2003)16: Singin' in the Rain (1952)17: Pulp Fiction (1994)18: Titanic (1997)19: The Wizard of Oz (1939)20: Star Wars - Episode V: The Empire Strikes Back (1980)21: Raging Bull (1980)22: Raiders of the Lost Ark (1981)23: Taxi Driver (1976)24: One Flew Over the Cuckoo’s Nest (1975)25: Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964)26: Goodfellas (1990)27: Some Like It Hot (1959)28: Chinatown (1974)29: The Silence of the Lambs (1991)30: The Lord of the Rings: The Fellowship of the Ring (2001)31: It’s a Wonderful Life (1946)32: Rear Window (1954)33: Annie Hall (1977)34: Saving Private Ryan (1998)35: The Seven Samurai (1954)36: North by Northwest (1959)37: Forrest Gump (1994)38: The Searchers (1956)39: All About Eve (1950)40: The Sound of Music (1965)41: The Graduate (1967)42: On the Waterfront (1954)43: The Dark Knight (2008)44: The Lord of the Rings: The Two Towers (2002)45: The Third Man (1949)46: Double Indemnity (1944)47: Sunset Boulevard (1950)48: Ben-Hur (1959)49: Alien (1979)50: Avatar (2009)51: The Bridge on the River Kwai (1957)52: Snow White and the Seven Dwarfs (1937)53: Blade Runner (1982)54: Jurassic Park (1993)55: The Apartment (1960)56: City Lights (1931)57: The Best Years of Our Lives (1946)58: West Side Story (1961)59: Toy Story (1995)60: The Shawshank Redemption (1994)61: Back to the Future (1985)62: Gladiator (2000)63: Modern Times (1936)64: The Good, the Bad, and the Ugly (1966)65: Fargo (1996)66: The Lion King (1994)67: King Kong (1933)68: Rocky (1976)69: Metropolis (1927)70: The Exorcist (1973)71: Avengers: Endgame (2019)72: 8 ½ (1963)73: A Clockwork Orange (1971)74: Doctor Zhivago (1965)75: The Philadelphia Story (1940)76: Butch Cassidy and the Sundance Kid (1969)77: The Bicycle Thief (1947)78: Tokyo Story (1953)79: American Beauty (1999)80: Close Encounters of the Third Kind (1977)81: The Deer Hunter (1978)82: Terminator 2: Judgment Day (1991)83: Sunrise: A Song of Two Humans (1927)84: The Matrix (1999)85: 12 Angry Men (1957)86: Spirited Away (2001)87: Touch of Evil (1958)88: L.A.
