Have you ever been an extra in a movie?

No I have not.

I did have the opportunity to be an extra in a live production of the Metropolitan Opera when they were on the road ("extras" are called "supernumeraries" in the opera world.) The mother of a college friend worked for the Met, and she was in charge of hiring locals for that purpose when the Met traveled to Boston. So she asked her son to ask his friends, and he asked me whether I would be interested. I would have loved to have done it, but I had a conflict that weekend. Ironically, I was in a play on campus!

Yeah,a few. Background shot in "So I married an axe murderer"
I was 'depressed guy hanging his head down in a bar while the protagonist meets a ghost' in "Tales of ordinary Magic" - an eight hour shoot in which I am maybe kind of fuzzily seen for 8 seconds.
...and both ate a bagel slightly offscreen and pretended to chat at a psychiatrist's convention in something pretty terrible that I can't quite remember the name of but I do have a DVD of somewhere and actually was listed in the credits plus those were really good bagels and coffee.

I'd forgotten about these high points in my entertainment career,thanks for the reminder.

Nope

Closest I ever came was chasing a suspect through the set of a live TV show. It was a sight, tripping over cables and wires for all the lighting and cameras. The guy worked at the station and was wanted for a homicide. Yes, I caught him.
🥴

No but I have in the UKs longest running soap opera, Coronation Street.

No, I have been on sets, and have friends that work in Hollywood.

Yes.

In a movie no...But I've been an extra for a number of TV shows

Nah, only as a consultant on the 2002 movie Black and White.

No but the place I rent was scouted for the movie Zola.

Unintentionally yes.
