Osborne and Gilliatt were married for five years (together for seven), and became the parents of his only natural daughter, Nolan. Osborne had an abusive relationship with his daughter: he cast her out of his house when she was 17; they never spoke again. Osborne and Gilliatt's marriage suffered through what Osborne perceived to be an unnecessary obsession on her part with her work, writing film reviews for "The Observer". "I tried to point out that it seemed an inordinate amount of time and effort to expend on a thousand-word review to be read by a few thousand film addicts and forgotten almost at once."
