Perhaps the prospect of sitting through his 92-year-old father’s one-man show had failed to fill Michael Douglas with vim and vigour.
And no doubt it was just an unfortunate camera angle which made him look stooped and far older than his 64 years.
Whatever the reason, Douglas looked a pale shadow of the dynamic Hollywood star who captured the heart of Catherine Zeta Jones.
While the 39-year-old actress was showing off her shapely pins in a short silver dress, Douglas was keeping warm with a jumper beneath his suit jacket as they arrived at the Kirk Douglas Theatre in Culver City, Los Angeles.
Catherine recently revealed that she washes her hair in beer and brushes her teeth with strawberries.
