The new series distanced itself from the "monster of the week" mandate that had characterized the original series from its inception; while there were plenty of aliens and monsters, they dramatize a specific scientific concept and its effect on humanity. Some episodes illustrating this difference include "Dark Rain" (biochemical warfare causes worldwide sterility), "Final Exam" (discovery of practical cold fusion power), "Stitch in Time" (a time traveler tinkers with history), as well as several episodes revolving around a human mutation known as Genetic Rejection Syndrome (humans mutating into violent creatures) as a result of a government experiment.
All series have been released in DVD format. In 1980 English writer and comedian Peter Cook starred alongside a host of celebrities in the LWT special "Peter Cook & Co.". The show included many sketches including a 'Tales of the Unexpected spoof' entitled "Tales of the Much As We Expected", which involved Cook as Roald Dahl explaining why he dropped the "n" in Ronald; the sketch ends with the fireplace spreading over the room.
Because it was aired on HBO, a premium cable television channel, it was one of the few anthology series to be allowed to have full freedom from censorship by network standards and practices as a result, HBO allowed the series to contain graphic violence as well as other content that had not appeared in most television series up to that time, such as profanity, gore, nudity and sexual situations, which could give the series a TV-MA rating for today's standards.
Originally 25 minutes per episode, the series was expanded to 50 minutes in 1962 and retitled The Alfred Hitchcock Hour. Hitchcock directed 17 of the 268 filmed episodes of Alfred Hitchcock Presents and one of the 50-minute episodes, "I Saw the Whole Thing" with John Forsythe. The last new episode aired on June 26, 1965, and the series continued to be popular in syndication for decades.
The seventh season of the American science fiction television series The X-Files commenced airing on the Fox network in the United States on November 7, 1999, concluded on May 21, 2000, and consists of twenty-two episodes. The season would be the last to feature co-star David Duchovny in full-time capacity. He would return in later seasons as an intermittent main character.
Season seven takes place after the destruction of the Syndicate, which marked the end of their long-running story arc. This season marks the end of various other story lines, most notably the revelation of Samantha Mulder's fate to her brother, Fox Mulder. In addition, because sister show Millennium was cancelled in 1999 without concluding any of the shows extended plot lines, Chris Carter felt he needed to bring closure for his cancelled show. As a result, the episode "Millennium" was written and produced.
