Collider has published a ranked list of the 10 most ambitious science-fiction films released over the past 25 years, compiled by senior writer Ryan Heffernan. The feature argues that sci-fi has always been defined by creative daring, tracing this back to ancient storytelling and early cinema, before assessing how filmmakers this century have used modern production techniques to build unprecedented worlds and stark visions of humanity's future.

Entries discussed include George Miller's "Mad Max: Fury Road" (2015), praised for its practical stunt work and its ability to convey worldbuilding through action rather than dialogue, and Alfonso Cuarón's "Children of Men" (2006), noted for its bleak dystopian setting, long takes and exploration of themes such as police militarisation and the refugee crisis. The full ranking extends to ten films in total, spotlighting both blockbuster spectacles and more understated, socially engaged works as examples of ambitious modern sci-fi filmmaking.
