Directors at Lightbox and John Bassett Theatre

This post can apply to actors as well, but I am specifically looking to get my blu-rays of Evil Does Not Exist and Burning signed at a premiere and visionary panel respectively. I'm looking for any tips for either venue as I've never been!

Any specific location I should be? Will I even have a chance or are these directors considered recognizable enough that they will be brought through the back? Thank you all!
