So what were actress Eliza Dushku and screenwriter-director Joss Whedon doing at Roe, a nightclub in San Francisco, Thursday evening?
Pitching Silicon Valley's best and brightest on supporting ThriveGulu, a charity for survivors of Uganda's civil war started two years ago by Dushku's mom, Suffolk University professor Judy Dushku.
Randi Zuckerberg—you know, the Zuckerberg who actually managed to graduate from Harvard—played with her band, Feedbomb.
Professor Dushku and Whedon spoke about the crisis in Uganda and the plan to build a center where victims of the war can recover from trauma.
There was also a silent auction—an unnamed tech mogul bid $20,000 for lunch with Whedon, and another donor matched that donation, we're told. Partygoers also swiped donations with Square, the mobile-payments service. Square CEO Jack Dorsey made a brief appearance.
But mostly people just had an amazing time.
Local radio personality Hooman Khalili introduced Dushku.
"Yes, I'm an actress with an African charity," Dushku joked. But her mom, Judy Dushku, has taught African politics for four decades.
Joss Whedon, known for Hollywood hits like "Buffy the Vampire Slayer" and "The Avengers," spoke about storytelling.
Dushku's boyfriend, former LA Lakers star Rick Fox, also addressed the crowd.
Items getting auctioned to raise money for ThriveGulu included "Buffy" and basketball memorabilia.
