Celebrity Rehab with Dr. Drew, later called simply Rehab with Dr. Drew, is a reality television show that aired on the cable network VH1 in which many of the episodes chronicle a group of well-known people as they are treated for alcohol and drug addiction by Dr. Drew Pinsky and his staff at the Pasadena Recovery Center in Pasadena, California. The first five seasons of the series, on which Pinsky also serves as executive producer, cast celebrities struggling with addiction, with the first season premiering on January 10, 2008, and the fifth airing in 2011. The sixth season, which filmed in early 2012, featured non-celebrities as treatment subjects, and the series name shortened to Rehab with Dr. Drew. Season 6 premiered on September 16, 2012.
According to a December 2009 New York Times article, Drew Pinsky, who was alarmed by tabloid portrayals of addiction as an indulgence of the rich and famous, and a group of independent producers, approached VH1 with a proposal for a reality television series which would authentically depict addiction, as a sort of media intervention. According to executive producer John Irwin, casting for the first season was the most difficult, as the representatives of the celebrities who had been arrested or had publicized bouts with addiction refused to speak with him and the other producers. The process became easier after the first season aired. Actor Tom Sizemore, for example, who was cast for Season 3, had been sought after since Season 1. Producers have reportedly offered actress Lindsay Lohan six figures to appear on the show. Pinsky, who focuses on the treatment side of the production, is not usually involved with casting, though he reportedly visited Rachel Uchitel personally in order to convince her to join the fourth-season cast.  A multitude of cameras are employed, which film twenty-four hours a day, seven days a week, during the 21-day treatment cycle. Because some dramatic incidents occur early in the morning when the camera crews are not present, automated cameras are mounted all over the clinic to capture them. The exception to this are the bathrooms, which nonetheless are equipped with microphones to monitor unusual sounds, such as patients attempting to use drugs. In addition to receiving the free treatment (which would normally be worth approximately US$50,000-60,000), the patients receive a salary for their appearance on the series, which is prorated, and distributed once a week as an incentive to stay. Celebrity Rehab spun off two other shows. The first spinoff is Sober House, which depicts Rehab alumni living for 30 days at a sober living facility, as an interim step for recovering addicts between the completion of rehab and their eventual return to their old life. The second spinoff is Sex Rehab with Dr. Drew, in which Pinsky and his staff treat celebrities for sexual addiction.  In May 2013, Pinsky announced that season six was the final season, citing the criticism leveled at him following the relapse and death of cast members, saying, "I'm tired of taking all the heat. It's very stressful and very intense for me. To have people questioning my motives and taking aim at me because people get sick and die because they have a life-threatening disease, and I take the blame? Rodney King has a heart attack and I take blame for that? It's just ridiculous." Pinsky insisted that his practices depicted on the show were the same ones he, Bob Forrest and Shelly Sprague engaged in for decades, with the sole difference being the presence of cameras. Despite his decision not to continue the series, Pinsky stated a number of people achieved sobriety due to Celebrity Rehab who would not have attained it without the show, and cites as the biggest success story Sizemore, who struggled with Pinsky's program for 10 years before finally achieving sobriety after being on the show.

executive producer John Irwin,
IN: Kenneth Charles Loach (born 17 June 1936) is an English director of television and independent film. His socially critical directing style and socialist ideals are evident in his film treatment of social issues such as poverty (Poor Cow, 1967), homelessness (Cathy Come Home, 1966) and labour rights (Riff-Raff, 1991, and The Navigators, 2001). Loach's film Kes (1969) was voted the seventh greatest British film of the 20th century in a poll by the British Film Institute. Two of his films, The Wind That Shakes the Barley (2006) and I, Daniel Blake (2016) received the Palme d'Or at the Cannes Film Festival, making him the ninth filmmaker to win the award twice.

Loach first joined the Labour Party from the early 1960s. In 1980s, he was in the Labour Party because of the presence of "a radical element that was critical of the leadership", but Loach had left the Labour Party by the mid-1990s after being a member for 30 years. During the 1960s and 1970s, he was associated with (or a member of) the Socialist Labour League (later the Workers Revolutionary Party), the International Socialists (later the Socialist Workers Party or SWP) and the International Marxist Group.  Involved in Respect - The Unity Coalition from its beginnings in January 2004, and stood for election to the European Parliament on the Respect list in 2004. Loach was elected to the national council of Respect the following November. When Respect split in 2007, Loach identified with Respect Renewal, the faction identified with George Galloway. Later, his connection with Respect ended.  Loach supported the Trade Unionist and Socialist Coalition in the London Assembly election, 2012. With the support of the activist Kate Hudson and academic Gilbert Achcar, Loach launched a campaign in March 2013 for a new left-wing party which was founded as "Left Unity" on 30 November. Loach gave a press conference during the launch of Left Unity's manifesto for the 2015 general election.  Together with John Pilger and Jemima Khan, Loach was among the six people in court who offered surety for Julian Assange when he was arrested in London on 7 December 2010. The money was forfeited when Assange skipped bail to seek asylum in the Embassy of Ecuador, London.
