Filming, which lasted from the summer of 2015 to the fall of the following year, saw Sickles and Santini shadow Buno and Levin in their local day-to-day activities. They ended up with 550 hours of raw footage. Aside from ravishing cinematography that turns Levin's early-morning SEPTA commute into an irreverent action sequence and makes the Neshaminy Mall parking lot pop like an oil painting, the most palpable technical aspect of Dina is how remarkably unobtrusive Sickles and Santini remain throughout. With the couple as our tour guides, we sit as silent eavesdroppers on the private conversations all of us have but none of us broadcast. Unremarkable nail salons, bowling alleys, and NJ Transit depots transform into raw confessional booths where Buno and Levin air their most most human hopes and insecurities — including plenty of frank talk about sex, a topic rarely discussed with this level of candor by anyone, let alone neurodiverse people.
