The disastrous meeting of the Muppets and ‘SNL’

The first season of "Saturday Night Live" featured some of the most cutting-edge comedy imaginable. Curiously, it also featured Jim Henson's Muppets. Henson and his singular brand of puppetry had found success with "Sesame Street," but Henson was concerned he was being pigeonholed as a children's entertainer and jumped at the opportunity to appear in a recurring segment on NBC's new program. The result was a bizarre train wreck that's detailed in this comprehensive retrospective.

'SNL' spinoffs have had mixed success

As “SNL” became more popular, Lorne Michaels sensed an opportunity to turn some of the show’s most popular sketches and characters into feature films.

After five seasons, Lorne Michaels quit ‘Saturday Night Live‘

Lorne Michaels left the show in 1980, citing burnout and disagreements with network executives. He tried several gigs, including a sketch comedy show called “The New Show” that was strikingly similar to “SNL,” but nothing stuck. He returned to "SNL" in 1985.

The first cast members were relatively unknown 'enlightened amateurs'

“SNL” producers aimed to cast relative newcomers for the show’s first season, convinced that amateurs would infuse the show with the countercultural spirit Lorne Michaels envisioned.

Comedy legend Catherine O'Hara quit 'Saturday Night Live' after just one week as a cast member

O'Hara was a star on the sketch show 'SCTV,' a sort of Canadian 'SNL' that eventually aired in the US. O'Hara was offered a role on 'SNL' when the future of 'SCTV' was uncertain, but when 'SCTV' was renewed, she quit 'SNL' to return to it. O'Hara was only a cast member for a week and never appeared on-air during that time, though she eventually hosted 'SNL' twice, in 1991 and 1992.

Eddie Murphy saved ‘SNL’ from getting canceled in the early '80s

A young Eddie Murphy kept "Saturday Night Live" afloat during the years Lorne Michaels left the show by turning even the most pedestrian material into something revelatory. Eventually, he pursued a wildly successful acting and stand-up career.

After several years of middling material and low ratings, showrunner Lorne Michaels returned in 1985 and brought a cast of Hollywood A-listers, including Anthony Michael Hall and Robert Downey Jr. The season is now called the “Weird Year" due to the use of more established actors, whose connection with the audience was limited.

Michaels doesn’t care when people say ‘SNL’ was funnier when they were younger

"Generally when people talk about the best cast I think, 'Well, that's when they were in high school,'" Michaels told "Today" in 2015. "Because in high school you have the least amount of power you're ever gonna have. ... Staying up with friends later on a Saturday is great, and people attach to a cast."
