Film production stills photographers

Hey all, wondering if theres any film production stills photographers here, any insights to your work and how you work around/within a film production (be it large or small) what does a typical day on set for you look like? How did you get into it? Is it the only work you do or do you work on other photo jobs/projects? Too many questions to ask! Just a curious fellow photographer who appreciates the stills that come from some productions… Thanks
