Which moment embarrassed you most?

Modelling tuxedos at the Oklahoma State Fair in 1971.

See my greatest fear!

When my trousers nearly fell down at Buckingham Palace. I was there to collect my OBE, and the suspenders for the beautiful Alexander McQueen suit I’d had made for the occasion went missing. Naomi Campbell was with me and we had a good laugh about it.

When you jump out of addiction and look back, things like drink-driving and sitting in crack houses are not good.

When I was starting out, in the early 90s, I had to fake an orgasm in a room full of male ad execs at an audition for a chocolate bar ad. It was grim.

Going to pieces while meeting John Squire, the lead guitarist of the Stone Roses, backstage after a gig. I completely lost the ability to speak. I told him I had the same guitars as he’d just used on stage, and when he asked me which ones, the words completely went out of my head and there was a huge pause, and then his wife tapped his shoulder and he wandered off.

Being on the cover of a magazine at 18 with the slogan: “Did she ruin The Godfather?”

I started stammering badly the first time I was on live radio, on Woman’s Hour on Radio 4. When I think about it now it brings me out in a cold sweat.

I recently had a dramatic fall on stage in Hungary. It was a massive stage – I was miles away from the audience – and I didn’t expect there to be two monitors in the middle of it. I went completely arse over tit and landed on my chin. First, I felt shock, pain, embarrassment, and then I felt lucky that I didn’t break any teeth or bite through my tongue. I asked for an ice pack for my chin, got up and finished the set.

Also my most triumphant: 2017 at the Royal Court. Julie Hesmondhalgh reads my psychologist’s report over two hours. Every excruciating intimate word of it. Extreme verbatim theatre. One night only.

Recently, sending a negative text about a person to that person.

The very first day that I was filming Top Gear, for which I was so unqualified because I’d only ever driven a Fiat Uno. I got into a DB7 Vantage Volante outside the Aston Martin factory, put my foot on the accelerator and bunny-hopped across the gravel because I’d forgotten to take the handbrake off.

I once walked up to Harriet Walter while she was having lunch on her own because I thought I knew her, and then when I got up to the table I realised I didn’t know her, I just recognised her because she was Harriet Walter.

I don’t get embarrassed.

I was doing The Seagull with Carey Mulligan and Kristin Scott Thomas on Broadway. I walked out on stage and looked at Carey and said: “I’ve no idea what to say.” It was pretty deep into the run and it took me by surprise.

I am in a public profession, so take your pick. It’s all embarrassing.

Wearing 90s ripped-at-the-crotch jeans at Rada during an unarmed combat session and showing everyone more than they bargained for.

Going on stage and saying, “Good evening Lyon!” I was in Marseille.

When I was 19 I worked at a gay bar while I was at drama school in London. One of the guys I worked with was Glaswegian and I learned the dialect from him. The acting teacher at the school said, “Liev, you’ve got the region but you’ve missed the character entirely” because I played Jimmy Boyle in a very camp Glaswegian accent.

One horrible afternoon in Chicago when I forgot my words in The Marriage of Figaro, in a role I’d sung hundreds of times.
