Michael C. Hall (born 1 February 1971) is a Golden Globe and Emmy Award-nominated actor, best known for his role of David Fisher in the HBO series Six Feet Under, and as Dexter Morgan in the Showtime series DEXTER. He also directed during Season Eight, directing the second episode titled "Every Silver Lining".
Hall's acting career began in the theater. Off-Broadway, he appeared in Macbeth and Cymbeline at the New York Shakespeare Festival, and in Timon of Athens and Henry V at the New York Public Theater, The English Teachers at the Manhattan Class Company (MCC), and the controversial play Corpus Christi at the Manhattan Theatre Club.
In 1999, director Sam Mendes cast Hall as the flamboyant Emcee in the revival of Cabaret, his first Broadway role. Sam Mendes also directed the film American Beauty, written by Alan Ball, and he suggested Hall for the role of deeply closeted David Fisher when Ball began casting the TV drama Six Feet Under.
Hall's work in the first season of Six Feet Under was recognized by a 2002 Emmy nomination for an Outstanding Lead Actor in a Drama Series and 2002 American Film Institute Award nomination for Actor of the Year. In addition, he shared in the Screen Actors Guild nomination for best ensemble cast all five years that the show was in production, winning the award in 2003 and 2004.
In 2003, Hall toured as Billy Flynn in the musical Chicago. His only film credit is the 2003 thriller Paycheck, and he also appeared in the 2003 TV-movie Bereft. In 2005 he returned to Off-Broadway theatre in the premier of Noah Haidle's Mr. Marmalade, playing the title character, an emotionally disturbed little girl's imaginary friend.
For his work on Dexter, Hall was nominated for the 2007 Golden Globe Award for best actor in a TV drama.
In a 2006 interview, Hall discussed his approach to the character of Dexter, saying:
- "I think Dexter is a man who... a part of himself is very much frozen, or arrested in a place that is pre-memory, pre-conscious, pre-verbal. Something very traumatic happened to him, he doesn’t know what that is. And I think on some level he wants to know. He denies his humanity, he describes himself as someone who is without feeling, and yet I think that he maybe suspects -- in a way that maybe isn’t even conscious yet when we first meet him -- that he is in fact a human being. Dexter's a unique killer in that his father saw his dark impulses, shined a light on them, and told Dexter that he saw them, he accepted them, that Dexter is good and that he is worthy of love. And I think that's what enables him to focus his energies in this unique way."
Born in Raleigh, North Carolina, Hall grew up an only child, a sister having died in infancy before his birth. When he was 11, his father died of cancer, and in a 2004 interview he recalled, "Certainly, for a young boy, there's no good age, but I think I was on the cusp of a time in my life where I was starting to reach puberty, to relate to my father. To have him... Something gets frozen. As you revisit it for the rest of your life, it's sort of this slow but hopefully sure crawling-out of that frozen moment." 
Hall graduated from Earlham College in Richmond, Indiana, in 1993. He later attended New York University's Master of Fine Arts program in New York City. In 2002, he married actress Amy Spanger; he played Billy Flynn opposite her Roxie Hart in the Broadway musical Chicago the summer after their wedding. The couple separated and divorced in 2006. On December 31, 2008, he married Jennifer Carpenter, who plays the character of Dexter Morgan's foster sister, Debra Morgan. They dated for a year and a half prior to getting married.
On 13 January 2010, his agent and spokesman confirmed that he was undergoing treatment for a treatable form of Hodgkin's lymphoma. The cancer is in remission and he is continuing treatment. Many castmates and friends made their concerns known to the media, some even admitting they had no idea Hall was battling Hodgkin's lymphoma because he never showed any signs of the disease. He expressed anxiety, mostly because he had avoided doctors since a childhood hernia operation.
Hall accepted his Golden Globe and Screen Actors Guild Award in 2010 while wearing a knitted cap over his bald head, having lost his hair to chemotherapy. On April 25, 2010, his wife, Jennifer Carpenter, announced that Hall was fully cured and was set to get back to work for a new season of Dexter. They dated for a year before eloping on New Year's Eve in 2008. It was Michael's second marriage. And then in the summer of 2010, Jennifer petitioned for divorce citing irreconcilable differences. The marriage was officially over that December.
n September 2012, Hall began dating Morgan Macgregor, who was an associate editor at the Los Angeles Review of Books, and they married on February 29, 2016.
Hall is the face of the Somalia Aid Society's Feed The People campaign. He has also worked with Kiehl's to promote a limited-edition skin care line that benefits the Waterkeeper Alliance, an environmental nonprofit that works toward clean and safe water worldwide. In 2011, Hall was the celebrity spokesperson for the Leukemia & Lymphoma Society's "Light the Night Walk" fundraising campaign.
