A vintage “Star Trek” episode about the perils of time travel has created unpleasant present-day repercussions for the CBS Paramount studio, which distributes the original television series. The author Harlan Ellison
, the screenwriter of the episode “The City on the Edge of Forever,” has filed suit against CBS Paramount, saying that the studio had not paid him merchandising and publishing revenue it earned from the episode, Variety reported. The episode, first broadcast in 1967, follows Captain Kirk as he travels back to [COLOR=#004276]the Great Depression[/COLOR] and falls in love with a social worker played by Joan Collins
. In his suit Mr. Ellison said he had not been paid for merchandise based on it, including a series of books and a talking Christmas tree ornament. Under the terms of a master contract with the [COLOR=#004276]Writers Guild of America[/COLOR], Mr. Ellison is entitled to 25 percent of revenues derived from the licensing of publication rights.
