Did Syfy borrow its latest "aliens among us" premise from a Buffy star?S

Controversy erupted over the weekend when Amber Benson, who played Tara on Buffy The Vampire Slayer, claimed one of Syfy's newly greenlit shows, Human Relations, was awfully similar to Drones, a film she wrote/directed with Adam Busch (Warren on Buffy.)

Both projects are about a guy working in an office who realizes his quirky, off-kilter coworkers are actually aliens plotting to destroy the world. Benson pointed out that her film — which hits theaters and DVD next March — had its trailer (above) premiere on Syfy's website in January, six months before Syfy greenlit Human Relations.

Here's the Drones trailer:

But Human Relations producer Scott Prendergast tells Airlock Alpha he's been working on his project since the mid-1990s, and it really is just a coincidence. (And to be fair, judging from the trailer, Drones seems more like a quirky romantic comedy than a paranoid "my bosses are evil" kind of deal. But it's always hard to judge from a trailer.)
