input: O'Brien's Late Night debuted on September 13, 1993, with Andy Richter chosen as O'Brien's sidekick. The premiere episode featured John Goodman (who received a "First Guest" medal for his appearance), Drew Barrymore, and Tony Randall. The episode featured a cold open of O'Brien's walk to the studio with constant reminders that he was expected to live up to Letterman, parodying a popular sentiment expressed in the media at the time. After seeming to be unaffected by the comments, O'Brien arrives at his dressing room and cheerfully prepares to hang himself. However, a warning that the show is about to start causes him to abandon his plans. O'Brien's inexperience was apparent and the show was generally considered mediocre by critics in terms of the host's ability. The Chicago Sun-Times' Lon Grankhe called O'Brien "nervous, unprepared and generally geeky" and Tom Shales wrote "As for O'Brien, the young man is a living collage of annoying nervous habits. He giggles and titters, jiggles about and fiddles with his cuffs. He has dark, beady little eyes like a rabbit. He's one of the whitest white men ever." (O'Brien wrote for The New York Times a satirical review of the first episode the day it aired titled "O'Brien Flops!", in which he told readers "Frankly, I was not impressed".) The originality and quality of the comedy, however, led by original head writer Robert Smigel, was widely praised. Although O'Brien benefited by comparison from the quick critical and commercial failure of the fellow new late-night The Chevy Chase Show, NBC only offered short-term contracts, 13 weeks at a time and once for six weeks, as widely reported by the press at the time. O'Brien was reportedly almost fired at least once in this period, but NBC had no one to replace him. According to Smigel, "We were basically canceled at Conan, and then they changed their minds in August of '94, gave us a reprieve." According to O'Brien a network executive told him, in regards to Andy Richter, he'd "never succeed until I 'got rid of that big fat dildo.' That was the tone of the conversations between us and the network." It was widely expected that the host of Talk Soup, Greg Kinnear would take over the role, but Kinnear turned down the opportunity and decided to pursue a career in acting. Stars like Tom Hanks agreed to appear on Late Night, which boosted audience awareness. Even Letterman, who admired O'Brien's comic sensibility, appeared as a guest to register his support. O'Brien's performance style improved through experience and he began to receive more favorable reviews and ratings the following year. With the ratings gradually improving over the course of two years, Late Night reached a new level of critical and commercial success in 1996. Tom Shales officially recanted his previous critical review with the headline "I was wrong", and O'Brien received his first Emmy writing nomination, which he has gone on to receive every year since.

input: Although Lundgren has never competed as a professional bodybuilder, he has been closely associated with bodybuilding and fitness since his role as Drago in the mid-1980s. Bodybuilding.com said, "Looking like a man in his 30s rather than his 50s, Lundgren is the poster boy of precise nutrition, supplementation and exercise application that he has practiced for over 35 years." In an interview with them, he claimed to often train up to six days a week, usually one-hour sessions completed in the morning, saying that "it's just one hour a day, and then you can enjoy the other 23 hours". Although he had begun lifting weights as a teenager, he cites co-star Sylvester Stallone as the man who got him into serious bodybuilding for a period in the 1980s after he arrived in the U.S. Stallone had a lasting influence on his fitness regime and diet, ensuring that he ate a much higher percentage of protein and split his food intake between five or six smaller meals a day. Lundgren has professed never to have been "super strong", saying that, "I'm too tall and my arms are long. I think back then [Rocky IV] I was working with around 300 pounds on the bench and squat." In a January 2011 interview with GQ he announced he is working on releasing his own range of vitamins and supplements. He wrote an autobiographical fitness book, Train Like an Action Hero: Be Fit Forever, published in Sweden (by Bonnier Fakta) on 9 August 2011, offering tips he learned over the years to work out in various situations (with a busy schedule and a lot of traveling). On 9 September 2014, Lundgren published Dolph Lundgren: Train Like an Action Hero: Be Fit Forever, a book which contains a detailed account of his earlier life and troubles. He cites a better quality of life as having inspired him to maintain his physical fitness. When in Los Angeles he trains at the Equinox Gym in Westwood and when at home in Marbella, Spain, he trains at the Qi Sport Gym in Puerto Banus. Dolph does, however, also like to spar and practice his karate in the gym to keep in top shape aside from weight lifting. He cites dead lifting and squats as the best exercises for muscle building. Lundgren is not a heavy drinker, but has professed on many occasions to being fond of tequila and cocktails, citing his knowledge in chemical engineering as "making really good drinks".
