5 Sci-Fi Movies That Set Up Sequels That Were Never Made

H.G. Wells, the renowned author of The Time Machine, The Invisible Man, and War of the Worlds, expressed strong dislike for one of the most significant science fiction films ever produced. Separately, several sci-fi movies established cliffhangers and plot points intended for sequels that were never actually created. These unfinished narratives promised the return of heroes and the introduction of new villains, leaving various storylines unresolved as the anticipated follow-up films failed to materialize for audiences.
