Blumenthal was hired as a fact-checker at Esquire magazine in the early 1970s, when he has 24. His first editorial job, he served under the editor Harold Hayes. In 1973, Nora Ephron, at the time an Esquire columnist, helped Blumenthal get a job at Playboy as an editor and writer. In addition to Esquire and Playboy, Blumenthal has also written for Salon.
Novels and nonfiction
Several of Blumenthal's books have been loosely based on his experiences in Hollywood, including the 1984 parody The Official Hollywood Handbook. Also in 1984, Blumenthal and his friend and fellow Playboy editor Barry Golson wrote a period-piece romance novella spoof called Love's Reckless Rash, published by St. Martin's Press under the pen name Rosemary Cartwheel. In 2013, the duo wrote Passing Wind of Love, a novel-length expansion of Love's Reckless Rash. Blumenthal wrote a pair of detective novel spoofs published by Simon & Schuster in 1985, both featuring private detective Mac Slade and set in modern-day Manhattan: The Tinseltown Murders and The Case of the Hardboiled Dicks. Blumenthal's 1988 nonfiction bookHollywood High is a history of the Los Angeles public high school founded in 1903 that was attended by numerous celebrities, including Lana Turner, Mickey Rooney, Judy Garland, John Ritter and Carol Burnett. In 1999, Blumenthal returned to literature with the comic novelWhat's Wrong With Dorfman? His agent sent it to about 20 publishers; it was rejected by all of them, and in 2000 Blumenthal decided to self-publish. In 2002 St. Martin's Press bought the book, republishing it the following year. The novel is about the midlife crisis of Hollywood screenwriter and hypochondriac Martin Dorfman, as he faces up to painful childhood memories and deals with a variety of physical ailments and professional setbacks. The Wall Street Journal called it "a funny and surprisingly moving story written at the intersection of shtick and angst", and Publishers Weekly described it as "frequently hilarious and unexpectedly touching." It was named one of January Magazine's favorite books of the year for 2000. Blumenthal's 2004 comic novel Millard Fillmore, Mon Amour was also published by St. Martin's. The book's central character, Plato G. Fussell, obsesses over writing a 10-volume definitive biography of Millard Fillmore, the 13th President of the United States. Fussell is a death-obsessed dysfunctional divorced wealthy loner who engages in a relationship with his psychoanalyst's wife after his first wife leaves him. His 2011 novel Three and a Half Virgins is also about a man whose wife leaves him: newly single Jimmy Hendricks is a lonely, middle-aged man revisiting his past by looking up his old girlfriends.
