Who Was Mark Blum? Age, Background, and Early Life
Mark Blum was born on 14 May 1950 in Newark, New Jersey. He grew up in a middle-class Jewish family in the suburbs. As a young boy, he never dreamed of becoming an actor. Trips into New York City to see Broadway shows made him fall in love with theatre, but he did not consider it a career path.
He attended the University of Pennsylvania, where he gravitated toward theatre classes. After graduating in 1972 as a theatre major, the University of Minnesota’s graduate program accepted him. This program worked in association with the famous Guthrie Theatre. Later, he toured with the National Shakespeare Company. He always credited his classical training there as the most important part of his development. “You can try anything you want to try,” he once told The New York Times about those early days. “It’s the old British theory. When you’re young, the best you can do is work out in the provinces and make as many mistakes as you can.”
In 1975, Blum arrived in New York City. He landed a small Broadway role, making his debut opposite Zero Mostel and John Dexter in “The Merchant” (1977). “What I admired in them was the compassion they brought to everything they did,” he later said about his legendary co-stars. “The key to Zero was that he had no spare time. That’s the way I try to lead my life at this time.”
Billy Vigar’s tragic death shocked the football world. Mark Blum’s death similarly shocked the theatre community. Both losses remind us how suddenly life can end.
Stage Career: The Obie Award Winner
Blum’s true home was the stage. He became a fixture of the New York theatre community over a 40-year career. Off-Broadway, he appeared in acclaimed productions of “Table Settings” (1980) and “Key Exchange” (1981). He worked with Playwrights Horizons repeatedly throughout his life.
The Obie Award Winning Role
In 1989, Blum won an Obie Award for his performance in “Gus and Al” at Playwrights Horizons. He played Al, a middle-aged, mediocre gay playwright who travels back in time to meet Gustav Mahler. Frank Rich of The New York Times praised Blum’s “weary-eyed portrayal.” Rich noted that Al’s self-pity was not self-martyrdom. Instead, it was “rueful hypersensitivity to the modern world with which he is perpetually at odds.”
Broadway Highlights
On Broadway, Blum appeared in nine productions. These included Neil Simon’s “Lost in Yonkers” (1991), where Rich called his Eddie “vivid.” He played an adversarial campaign manager in Gore Vidal’s “The Best Man” (2000). Ben Brantley wrote that Blum gave off “the heady nervousness that the audience is meant to feel vicariously.” Other Broadway credits included “The Graduate” (2002), “Twelve Angry Men” (2004), and the 2012 revival of “The Best Man.” His last Broadway turn came in “The Assembled Parties” (2013). There, he embodied “the threats implicit in combative masculinity,” wrote Brantley.
Film Career: From Madonna to Crocodile Dundee
Blum’s film career took off in the 1980s. His most famous role came in 1985. He played Gary Glass opposite Madonna and Rosanna Arquette in “Desperately Seeking Susan.” He portrayed the husband caught in a web of mistaken identity and romantic confusion.
The following year, he landed a supporting role in the Australian blockbuster “Crocodile Dundee” (1986). He played Richard Mason, a smooth-talking journalist. The film became a massive worldwide hit.
His other film credits included “Blind Date” (1987) with Bruce Willis, “The Presidio” (1988) with Sean Connery, and “Shattered Glass” (2003). He also appeared in “Step Up 3D” (2010), “Coin Heist” (2017), and “Sister of the Groom” (2020), which released after his death. Lenny Rush became a star at a young age.
