The former 'West Wing' star - who has two sons with wife Sheryl Berkoff - hasn't drank alcohol since 1990 but admits that every decade, he finds another vice he needs to "get rid off".
He told the Daily Telegraph: "Every 10 years of sobriety, I find something else I have to get rid of. I never thought I'd have a junk food thing but at the moment I find myself in the pantry at 3.30am eating Doritos and cheese strings, washed down by a Coke, and it's everything I love: it's secret, so satisfying, and a little self-destructive."
Following the wave of the #MeToo movement, intimacy coordinators have grown in popularity on films and TV shows to work on love scenes, and Rob thinks that has taken away "part of the fun" for viewers.
He said: "Part of the fun was 'were they doing it or not?' Think about An Officer And A Gentleman, The Postman Always Rings Twice, Body Heat'or 9 1/2 Weeks... Of course they won't be making any movies like that again, so in a way we needn't worry, but part of the thing was 'how real is real?' And now we know that none of it is."
