About Glenn Quinn

Lived 1970 – 2002 (aged 32). Glenn Quinn was an Irish actor, film actor and television actor.

Glenn Martin Christopher Francis Quinn (28 May 1970 – 3 December 2002) was an Irish actor, best known for his portrayal of Mark Healy on the 1990s family sitcom Roseanne and his role as the half-demon Allen Francis Doyle on Angel, a spin-off series of Buffy the Vampire Slayer.

Early life Glenn Martin Christopher Francis Quinn was born in Dublin on 28 May 1970, the son of Bernadette Quinn (née Brady) and Murty Quinn. His father was a musician and singer with the Miami Showband, who had seven No. 1 hits in the 1960s and 1970s. He was raised in the Cabinteely suburb of Dublin, and attended Clonkeen College. In 1988, at the age of 18 he moved to the United States along with his mother and two sisters, Sonya and Louisa, who settled in Los Angeles.

Career In 1990, Quinn did television commercials for Pepsi and Ray-Ban, appeared in the music video for the Richard Marx song "Satisfied", and had his first speaking line in the pilot of Beverly Hills, 90210 after having endured eight separate auditions for the roles of Brandon Walsh and Steve Sanders

In 1990, Quinn was cast as the recurring character Mark Healy, Becky Conner's boyfriend and later husband, in Roseanne in its third season and remained a series regular through its ninth and final season in 1997. In 1992, while still on Roseanne, Quinn also took a main role on the American and British TV series Covington Cross and in the same year, co-starred with Holly Marie Combs in the slasher film, Dr. Giggles. In an interview with The Irish Times, he said of his accent, "I've been hiding it for so long that it's amazing to have some freedom. It was like putting on an old pair of shoes. It's bringing my soul back to life."

His last film was the dark comedy, R.S.V.P. (2002).

Personal life Quinn struggled with substance addiction in the time following Roseanne, a timeline confirmed by co-star Michael Fishman and Quinn's sister. Unable to maintain sobriety, he was eventually bought out as the owner of Goldfingers nightclub in Los Angeles in 1997. He returned to Ireland in 1997 to be with his family, who supported him in achieving short periods of sobriety and spent time in a drug and alcohol rehabilitation centre. He would later return to Los Angeles to resume his acting career.

Death On 3 December 2002, at the age of 32, Quinn was found dead at a friend's home in North Hollywood, California, where he had been staying for a few months. An autopsy found that he had died from an accidental drug overdose earlier that day.

During production of the tenth season of Roseanne, which aired in 2018, it was decided that Quinn's role of Mark Healy would not be recast, and his role was written off the show as having died years ago. It introduced, however, a new Mark Healy, the son of Darlene Conner and David Healy. The series paid tribute to Quinn at the end of one of its episodes, "Eggs Over, Not Easy."

In 2019, during Entertainment Weekly 20th-anniversary reunion of the cast of Angel, actor David Boreanaz stated that "Glenn played a great character, but also became a really close friend of mine. God rest his soul."
