At least in the United States, smoking is something fewer and fewer people take up these days. This obviously wasn't the case back in the 50's through the 80's, where cigarettes were commonly smoked out in public.
So whenever I see a period movie or show, filmed in the 2020's but taking place in the 60's, there's frequent scenes where characters are smoking cigarettes in a bar or stress-smoking to the filter after a stressful conversation. And I think to myself, "are these actors all smokers? In this day and age? Or is that an unlit prop ciggy with VFX smoke done in post?"
Are fake cigarettes common in film production now, or are these still typically the real deal?
Just in case someone important reads this:
I really wish movie makers would drop the ‘smoking is {cool,badass,…whatever} trope.’ I’m happy whenever I find that a whole cast never touches a cigarett on camera (think, How I Met Your Mother or The Big Bang Theory)
How I Met Your Mother literally had an episode only about smoking, revealing that everybody in the main group has smoked at one point, and they all do in that episode.
Besides that, isn't the "smoking is cool" phase in movies a thing of the past already? Most movies don't show anyone smoking, and if, I would say it's most often not the hero, but often some shady guys.
