1. It Happened One Night (1934) Columbia Pictures Watch on: Netflix UK and IrelandStarring Clark Gable and Claudette Colbert, It Happened One Night was the first movie to ever win in all five of the major Oscars categories: Best Picture, Best Director, Best Actor, Best Actress, and Best Screenplay. 2. Gentleman's Agreement (1947) 20th Century Fox Watch on: Netflix USControversial in its time, Gentleman's Agreement stars Gregory Peck as a journalist who pretends to be a Jewish man in order to research a story on anti-Semitism in New York City. 3. All About Eve (1950) 20th Century Fox Watch on: Netflix Canada and moreYou've probably heard of All About Eve, which stars Bette Davis and holds the record for the highest number of Oscar nominations (which has now been matched by Titanic and this year's La La Land). 4. The Godfather (1972) Paramount Pictures Watch on: Netflix Australia, India, Japan, and moreThe Godfather was the highest-grossing film ever at the time of its release, and according to the American Film Institute, it is the second-greatest film of all time, after Citizen Kane. 5. The Godfather Part II (1974) Paramount Pictures Watch on: Netflix Australia, India, Japan, and moreThe sequel to The Godfather was actually considered by some critics to be superior to the original (shocking, I know) and was the first sequel to win the Oscar for best picture. 6. Rocky (1976) United Artists Watch on: Netflix AustraliaThere's no doubting that Rocky is an iconic movie – it was shot in less than a month, became the highest-grossing movie that year, and has like a thousand sequels. (OK, maybe not a thousand. It has six.) 7. Annie Hall (1977) United Artists Watch on: Netflix UK and AustraliaAnnie Hall is considered to be one of the greatest comedies ever written and, as well as Best Picture, also won Oscars for Best Actress, Best Screenplay, and Best Director. 8. Out of Africa (1985) Universal Pictures Watch on: Netflix Canada, Mexico, and moreOut of Africa is based (pretty loosely) on the true story of Danish author Karen Blixen, who moved to Kenya with her husband and promptly fell in love with an English army officer. Also, Meryl Streep! 9. Rain Man (1988) United Artists Watch on: Netflix AustraliaStarring Dustin Hoffman and a young, pre-Mission Impossible Tom Cruise, Rain Man earned eight Oscar nominations and won in four major categories – Best Picture, Best Actor, Best Director, and Best Screenplay. 10. The Silence of the Lambs (1991) Orion Pictures Watch on: Netflix AustraliaThe Silence of the Lambs was only the third film to win Oscars in all five major categories, AND it's the only horror film to ever have won for Best Picture. It's great, but probably don't watch it alone. 11. Schindler's List (1993) Universal Pictures Watch on: Netflix Canada, Australia, and moreStarring Liam Neeson, directed by Steven Spielberg, and shot in black and white (apart from that little girl's red coat, of course), Schindler's List is another one considered to be one of the greatest movies of all time. 12. Braveheart (1995) 20th Century Fox Watch on: Netflix US, Australia, and moreBraveheart stars Mel Gibson doing a Scottish accent and tells the story of the First War of Scottish Independence, which happened in the 13th century. Also, it's rated R for "brutal medieval warfare", if you're into that. 13. Titanic (1997) 20th Century Fox Watch on: Netflix UK and IrelandYou don't need me to tell you about Titanic – it won, like, all the Oscars, holds the joint record for number of nominations, and sparked a decades-long debate about whether or not Leo could've fit on that door (spoiler: meh). 14. Shakespeare in Love (1998) Universal Pictures Watch on: Netflix USShakespeare in Love is based (very) loosely on the life of (duh) William Shakespeare, while he was writing Romeo and Juliet. Also, Gwyneth Paltrow does a bizarrely good English accent in it. 15. American Beauty (1999) DreamWorks Pictures Watch on: Netflix Canada, Australia, and moreAmerican Beauty stars Kevin Spacey as a man who has a midlife crisis when he starts fancying his teenage daughter's friend. It won five major Academy Awards, and you'll probably recognise that iconic falling rose petals scene. 16. A Beautiful Mind (2001) DreamWorks Pictures Watch on: Netflix Australia, India, and moreA Beautiful Mind tells the true story of John Nash (played by Russell Crowe), a mathematician who developed paranoid schizophrenia at a young age. The movie won four Academy Awards and was nominated for a total of eight. 17. Chicago (2002) Miramax Films Watch on: Netflix CanadaOne of only a few musicals to ever win Best Picture, Chicago tells the story of Roxie Hart, a woman who murders her husband and goes to prison, and whose solo songs will leave you bopping for days. 18. The Lord of the Rings: The Return of the King (2003) New Line Cinema Watch on: Netflix Canada, India, Mexico, and moreReturn of the King is the second and final sequel to ever have won an Oscar for Best Picture (after The Godfather Part II, duh), and the only fantasy movie ever to do so. 19. The Departed (2006) Warner Bros. Watch on: Netflix Canada and AustraliaDirected by Martin Scorsese and starring Matt Damon, Jack Nicholson, and Leonardo DiCaprio, The Departed won four major awards at the Oscars and is considered to be one of the best movies of the noughties. 20. No Country for Old Men (2007) Miramax Pictures Watch on: Netflix US, India, Mexico, and moreThe Coen brothers' No Country for Old Men is described as a "neo-western neo-noir thriller", and if that doesn't fascinate you, I don't know what will, tbh. 21. Slumdog Millionaire (2008) Fox Searchlight Pictures Watch on: Netflix Australia, Japan, and moreSlumdog Millionaire was the movie that shot a lil' baby Dev Patel to international fame. It won eight Oscars – the most of any film that year – as well as a whole bunch of other awards, and it's Fox Searchlight Pictures' highest-grossing film ever. 22. The Hurt Locker (2009) Summit Entertainment Watch on: Netflix Canada, India, Japan, and moreSure, we're talking about Best Picture here, but you probably remember The Hurt Locker as being the only movie by a female director (Kathryn Bigelow, fyi) to ever win Best Director. Sigh. 23. The King's Speech (2010) The Weinstein Company Watch on: Netflix UK, Canada, and moreStarring Colin Firth as King George VI, The King's Speech won a whole bunch of awards, but most importantly it's great because you get to see a (fake) member of the royal family do a lot of swearing. 24. Argo (2012) Warner Bros. Watch on: Netflix Australia, India, and moreDirected by Ben Affleck, Argo tells the true(-ish) story of Tony Mendez, who led the rescue of six US diplomats from a hostage situation in Iran, all while pretending that he was just making a sci-fi movie. It's insanely tense. 25. 12 Years a Slave (2013) Fox Searchlight Pictures Watch on: Netflix Australia, Canada, India, and moreAdapted from the memoirs of Solomon Northup, 12 Years a Slave tells the story of an African-American man who was kidnapped from Washington, DC, and sold into slavery in the mid-1800s. 26. Birdman or (The Unexpected Virtue of Ignorance) (2014) Fox Searchlight Pictures Watch on: Netflix UK, Japan, and ItalyDirected by Alejandro G. Iñárritu, Birdman stars Michael Keaton as a washed-up actor who's haunted by a superhero role in his past. It's all filmed in one shot, and it's literally awesome. 27. Spotlight (2015) Open Road Films Watch on: Netflix USSpotlight tells the true story of the investigative journalists of the Boston Globe who, in the early noughties, uncovered the widespread sexual abuse of children by a large number of Roman Catholic priests. It's not exactly a lighthearted watch, but it's incredibly important.
