It’s incredible to think that this year’s Sundance Film Festival is the first time Eli Roth has been to Park City with a pic. As the Knock Knock director told me when he came by our DeadlineNow studio, the story behind getting the psychological thriller into production and bringing Keanu Reeves on board as both the lead and as an executive producer is even more incredible. You have to watch the clip above.

And remember, there’ll be more DeadlineNow @Sundance 2015 interviews throughout the festival, so look out.
