In 1984, two years after the series went off the air, Bill Bixby offered Nicholas Hammond a chance to reprise his titular role from The Amazing Spider-Man (1977) TV series in a proposed Hulk/Spider-Man TV-movie crossover that would have been distributed by Universal Pictures and Columbia Pictures. Hammond agreed to the offer, but Universal Studios eventually canceled the project, claiming that Lou Ferrigno was unavailable. However, Ferrigno said that he was never contacted about the project, and had no knowledge of it until he discovered the information while working on his autobiography in 2003.

_Incredible Hulk, The (1977) (TV)_ (The pilot), _Incredible Hulk: Death in the Family, The (1977) (TV)_ and _Incredible Hulk: Married, The (1978) (TV)_, which all originally aired as two-hour TV-movies, are edited for syndication, allowing each installment to be seen as two-part episodes.
