A personal documentary can be for any occasion.  Here are just a few examples:

Family History – Hear the stories of what it was like “in the old days” from an older parent or grandparent.

Wedding Rehearsal Dinner – Share the story of how you met before you say “I do.”

Anniversary Party – Honor your parents many years of commitment with the story of their lives together.

Milestone Birthday – Highlight your guest of honor with a story of a life well lived so far.

Bar/Bat Mitzvah – Be a hit with the teen set and show your guests what your 13-year-old is all about.

Retirement – Pay tribute to the contributions of a colleague as you bid them farewell.
