Mock died had three different versions of what was playing on the radio as he passed. Was it Ella Fitzgerald’s “ATisket, A-Tasket,” Mock’s favorite song; “After You’ve Gone”; or something else?

“Which is true, and which gets immortalized?” Purnell says. “They were probably listening to the jazz station, so all those songs probably came on. It’s funny what gets committed to history and what becomes legend.”

The specter of AIDS looms large in “Unstoppable Feat.” Considering the life not lived and the dances not made was sobering for Purnell.

“It made me cry a lot, but it also galvanized me, because it made me feel like, ‘OK, there’s a lot of time and space to make up, and I have some very big shoes to fill,” Purnell says. “I think when we learn about these histories, it’s sad, but it’s also a reminder that we have a charge to keep these legacies and these histories going.”

Through the filmmaking, Purnell has gotten to know Mock as a man and now thinks of him as an old friend.

“I feel like I have this extra ancestor that I never knew about and he’s permanently in my psyche,” Purnell says. And if he could somehow travel through the space-time continuum and meet Mock?

“I would give him a really, really big hug. I would say, ‘Thank you,’ ” Purnell says.

“And then I probably would just talk about boys. The Castro was poppin’! I want to know.”
