Spacey will take the lead as a formerly high-powered lobbyist who eventually wound up in prison over his indulgence in bribery schemes and fraudulent dealings with Indian casinos.
Hickenlooper was actually a co-director on the legendary Hearts of Darkness: A Filmmaker’s Apocalypse, the documentary about the making of Apocalypse Now. He also directed the excellent Mayor of the Sunset Strip, about Rodney Bingenheimer, and the okay Edie Sedgwick bio Factory Girl.
Snider’s most notably credit is as a co-writer, alongside David Cronenberg, on Dead Ringers.
This sounds like an interesting project for Spacey. He does well playing smarmy, arrogant assholes and Abramoff is a prime candidate. You can read about his dealings here but, as a taster, he was accused of defruading Native American tribes out of $25m for lobbying activities.
