Just in time for Mother's Day, Blair Underwood has written a new book, A Soldier's Wife: My Mother, the Marvelous Mrs. Marilyn A. Underwood, which pulls from his mother's writings and diaries to tell the story of her life. In addition to collaborating with Ylonda Gault on the book itself, he also teamed with his sister Marlo Underwood to perform the audiobook.

To celebrate the book's release and his mom, Underwood visited with Mashable Entertainment Editor Kristy Puchko at the Say More studio in New York. Together they discussed Marilyn's life, her struggle with multiple sclerosis, her faith, and her deep love of fashion. Beyond that, Underwood shared how he found his mother's voice, and if he'd ever consider AI for such a job.

In their last conversation, Underwood had also spoken about how Sidney Poitier was a mentor to him as a young Black actor in Hollywood, and how Michael B. Jordan's Oscar speech for Sinners' tapped into Poitier's legacy.

A Soldier's Wife: My Mother, the Marvelous Mrs. Marilyn A. Underwood is now available in bookstores and on Audible.
