In 1960, George Pal directed the film The Time Machine, with screenplay by David Duncan, largely based on the novel; however some significant changes were made. The name "George" (after the author, Herbert George Wells) was given to the time traveler in the film. Traveling through different times, George reaches the year 802,701 A.D. where he finds a girl drowning in a "shallow", to which her race, the Eloi, are indifferent. He rescues her and learns her name, Weena. Unlike the novel, George does not leave Weena dead. He rescues Weena and the Eloi, returns to his own time, and then to Weena's time to be reunited with her. Weena was played by Yvette Mimieux.

Sunn Classic Pictures produced the television film The Time Machine in 1978. Some major changes were made to the story. The time traveler is Dr. Neil Perry, a scientist from the 1970s. The story takes place in the United States instead of the United Kingdom. He travels to the far future and befriends Weena, who tells him the Morlocks take the Eloi for an unknown purpose. Perry visits the Morlocks to rescue Weena's brother. He also teaches the Eloi how to defend themselves. He returns to his own time after completing his mission and again goes to the future to reunite with Weena. Priscilla Barnes played the role of Weena.

Another movie with the same name was produced by Arnold Leibovit and directed by Simon Wells in 2002. Weena has been renamed Mara (played by Samantha Mumba). Dr. Alexander Hartdegen is an inventor in 1899 at Columbia University who devotes his life to making a time machine after the murder of his girlfriend Emma. He travels to the year 802,701 A.D., meets the Eloi, and is nursed back to health by Mara. He rescues Mara and starts a new life with her and the Eloi.

• The PBS children's series Wishbone, in which the title dog character recreates works of popular literature, had an episode entitled "Bark to the Future" in which Wishbone (voice of Larry Brantley) took on the role of the Time Traveler. Though heavily abridged and toned down, the tale was told effectively and the world of 802,701 A.D. was well-presented, with pink-clad and pink-haired Eloi and creepy, monkey-like Morlocks. Weena was played by series regular Lisa-Gabrielle Greene.
