/u/StopReadinMyUsername on reddit combined the average ratings (Critic's & Users) from IMDb, Rotten Tomatoes, Metacritic and Letterboxd, and then weighted and tweaked the results with general film data from iCheckMovies and IMDb to reveal the 1001 Greatest Movies of All Time.
A collection of science fiction movies and television shows that attempt some degree of scientific accuracy, with technologies or scenarios that may be nonexistent in today's world but are at least realistic (if only theoretical). That is to say, they don't rely on magic or fantasy (or anything that departs significantly from mainstream theory) to propel their plot.
This is not to say that some of the line-up here don't take a few speculative leaps, but they at least begin from a place grounded in credible research and theory, from where they then develop their more extravagant premises.
Yes, listing time travel films here is a cheat, but I've only included a few, and only those that make some attempt to explain their paradoxes and/or take their temporal consequences seriously.

In its first film season, 1927–28, this award (like others such as the acting awards) was not tied to a specific film; all of the work by the nominated cinematographers during the qualifying period was listed after their names. The problem with this system became obvious the first year, since Karl Struss and Charles Rosher were nominated for their work together on Sunrise but three other films shot individually by either Rosher or Struss were also listed as part of the nomination. The second year, 1929, there were no nominations at all, although the Academy has a list of unofficial titles which were under consideration by the Board of Judges. In the third year, 1930, films, not cinematographers, were nominated, and the final award did not show the cinematographer's name.
Finally, for the 1931 awards, the modern system in which individuals are nominated for a single film each was adopted in all profession-related categories. From 1939 to 1967 with the exception of 1957, there were also separate awards for color and for black-and-white cinematography. Since then, the only black-and-white film to win is Schindler's List (1993).
Floyd Crosby won the award for Tabu in 1931, which was the last silent film to win in this category. Hal Mohr won the only write-in Academy Award ever, in 1935 for A Midsummer Night's Dream. Mohr was also the first person to win for both black-and-white and color cinematography.
No winners are lost, although some of the earliest nominees (and of the unofficial nominees of 1928–29) are lost, including The Devil Dancer (1927), The Magic Flame (1927), and Four Devils (1928). The Right to Love (1930) is incomplete, and Sadie Thompson (1927) is incomplete and partially reconstructed with stills.
The first nominees shot primarily on digital video were The Curious Case of Benjamin Button and Slumdog Millionaire in 2009, with Slumdog Millionaire the first winner. The following year Avatar was the first nominee and winner to be shot entirely on digital video.
In 2018, Rachel Morrison became the first woman to receive a nomination. Prior to that it had been the last Academy Award category to never nominate a woman.
This list is drawn from the second edition of "The New York Times Guide to the Best 1,000 Movies Ever Made", published in 2004. It contains a selection of 1000 reviews that have been printed in The New York Times in a time period of over seven decades. The majority of movies in this book are among the "10 Best Films" chosen by New York Times critics at the end of each year.
The Saturn Award for Best Science Fiction Film is one of the Saturn Awards that has been presented annually since 1972 by Academy of Science Fiction, Fantasy & Horror Films to the best film in the science fiction genre of the previous year.
