First, a few highlights from Wikipedia's page on "Life Day":
Generally, The Star Wars Holiday Special has received a large amount of criticism, both from Star Wars fans and the general public. David Hofstede, author of What Were They Thinking?: The 100 Dumbest Events in Television History, ranked the holiday special at number one, calling it "the worst two hours of television ever."
At one Australian fan convention, [George Lucas] reportedly said, "If I had the time and a sledgehammer, I would track down every copy of that show and smash it." In an online chat with fans, he reportedly said: "The Holiday Special does not represent my vision for Star Wars." In an interview with Maxim in May 2002, Maxim asked the question, "Any plans for a Special Edition of the Holiday Special?" In response, Lucas said, "Right. That's one of those things that happened, and I just have to live with it."
On February 8, 2006, Harrison Ford made an appearance on Late Night with Conan O'Brien, and during the interview, Conan O'Brien brought up the special, and began asking various questions regarding it, such as inquiring whether he remembered making it. Ford said nothing, but looked away and shook his head nervously, then saying he had no memory of it whatsoever and it, therefore, "doesn't exist." The audience responded with laughter and applause. O'Brien then asked Ford what he would think if he played a clip of the special on the show, Ford jokingly grabbed him, then said that "[he'd] never seen it, maybe it'll be nice." Humorously acting anxious and distracted, Ford suffered through the clip (which featured a scene showing Ford as Han Solo telling Chewbacca and his wife that they are "like family" to him), and then muttered a gruff, sarcastic "thank you" to O'Brien, before continuing with the interview to promote his then newest film, Firewall.
On the 2010 television program Times Talk, New York Times columnist David Carr asked Carrie Fisher about the Holiday Special; she said that she made George Lucas give her a copy of the Special in exchange for recording DVD commentary for the Star Wars films. She added that she shows it at parties, "mainly at the end of the night when she wants people to leave."
Happy Life Day, everybody.
