Do the actors come and go during every single showing or do they go during the premiere?

It is a "hit-or-miss". Actors are regular people, too, and enjoy the movies. It's in Hollywood so you have a good chance to spot one or two.

Actors are under contract for premieres and promos. You will not see to many actors randomly going there just to watch a movie.

Let me put it this way, besides premieres or a Walk of Fame Ceremony, Stars do not hang out on Hollywood Blvd. Sorry.

I've purchased tix fur special events but other than that I have not seen any actors just hanging out watching movies. I rarely see famous people in that area unless there's a special event.

Only if it's publicized and included in your ticket package will you see what is offered! I was lucky enough, though I got there late due to the street being closed bcuz it was the same day as the NAACP IMAGE AWARDS, I was late to see Dumbo and paid for the VIP TICKETS so they missed the most important moments but as we walked from the parking garage to the front on Hollywood Blvd I got to see John LEGEND walking the Red carpet to the event!🤩😍

I've been there many times. I have never seen an actor. I've seen a producer one time before the movie.

Premiere definitely. To be honest celebrities go see movies but usually different entrance, they sneak in "back way" to enjoy whatever movie want to see or arrange private screening.
