Michael J. Fox's first audition was deemed terrible by 'Gary Goldberg' because Fox came off too smart-aleck. Casting director 'Judith Wiener' really liked Fox and begged Goldberg to see him a second time. Fox took a different approach, the audition went great, and Fox was offered the part.
The cast wanted to end the show with the entire Keaton family dying in a plane crash. They absolutely didn't want to do a reunion show in the future.
The character 'Steven Keaton' was ranked #12 in TV Guide's list of the "50 Greatest TV Dads of All Time" (20 June 2004 issue).

In March 2008, creator Gary David Goldberg wrote an essay for The New York Times speculating about what Alex Keaton's political beliefs would be now. Goldberg said that Keaton, as a "true Conservative Republican," would probably no longer feel comfortable in the Republican Party of the late 2000s, "a party whose legacy will include Terri Schiavo and Hurricane Katrina, [and]...waging war against science." Goldberg said that Keaton would have supported McCain in 2000 but no obvious candidate in the 2008 race. He also said that he and Michael J. Fox have different ideas about Keaton's current career; Goldberg thinks Keaton is a pro bono lawyer for the Children's Defense Fund, while Fox believes Keaton is finishing a prison sentence.
