If your thirst for information regarding Quantic Dream's upcoming psycho-killer drama, Heavy Rain, has yet to be slaked, you may want to check out the above video. It features an interview with the game's executive producer, Guillaume de Fondaumiere. No OMGMegatons are dropped during the duration of said interview, but Fondaumiere does explain the inspiration behind the game's story, and gives a few more details into the two out of the four characters the developer has chosen to reveal.
Try not to get too attached to these protagonists -- Fondaumiere also reminds us in this video that any of them could die at the drop of a hat. Or rather, a knife, assuming said knife drops into one of their more vital locations.
