Time Machine: The Journey Back is a documentary film, produced in 1993 for airing on PBS stations. It was hosted by Rod Taylor and produced and directed by Clyde Lucas.

The special was made about the Time Machine prop, now owned by ex-producer Bob Burns, to answer where it had been since the making of George Pal's 1960 classic film The Time Machine. Many believe it was made about the Making of the film, it was not. During filming, Burns surprised director Clyde Lucas by having Gene Warren, Sr. drop by during filming. Warren, the award winning effects creator for the original movie, kindly consented to an on-air interview in which he discussed creating the special effects for the film. This led to an interview with one of Warren's partners, Wah Chang, in Northern California. Chang and Warren shared more details about creating the effects and how the little Time Machine prop was made.

Lucas contacted the original screenwriter, David Duncan, who agreed to write a mini-sequel to George Pal's classic. The mini-sequel reunited George (Rod Taylor) with Filby (Alan Young). Lucas first filmed Whit Bissell for the opening, recreating his role as Walter. It would be Mr. Bissell's last acting performance. Note: Mr. Bissell is wearing one of the jackets Rod Taylor wore in the original film.

TMJB won a Saturn Award, Telly Award, "special feature" on George Pal's The Time Machine DVD released by Warner Bros. and was featured in Starlog Magazine.

In this follow up to the Time Machine, Filby is still the caretaker of his friend George's house ten years following George's trip to the future. Filby is then surprised to see his old friend return to his home to retrieve some books to help in his quest to rebuild humanity. During the stay, Filby implores his good friend to stay and resume his life there. However, George refuses and tells James that he has chosen to remain in the future. Also, it is a sad return for George due to the fact that at the time he returns it is just prior to the beginning of World War I and he does all he can to try to not reveal the tragic future of his good friend.
