Arnold Schwarzenegger's new memoir has debuted with disappointing sales.
The 65-year-old star speaks in candid detail about his cheating scandal in Total Recall: My Unbelievably True Life Story.
Despite a whirlwind publicity tour, fans don't seem keen to read about the infidelity.
The book, which debuted October 1 in the US, sold a meagre 21,000 copies in its first week, according to Nielsen Bookscan reports.
By comparison, J.K. Rowling's fictional tome A Casual Vacancy sold roughly 350,000 copies in six days, according to The Hollywood Reporter.
The adult novel topped Publishers Weekly's US bestseller list for hardcover fiction last week, while Arnold's ranked third in the hardcover nonfiction category.
The Terminator actor discusses his covert relationship with family housekeeper Mildred Baena in the tome.
He also reveals estranged wife Maria Shriver suspected he was unfaithful long before she discovered he fathered a love child.
Arnold still hopes Maria will give their relationship another chance.
"You can call this denial but it's the way my mind works," he writes.
