What we can say is this. How do you define an “interactive movie”? I define an interactive movie as a series of prerecorded videos, where their order is triggered by player decisions.

Heavy Rain differs in this respect since their are no prerecorded movies, you get to control the character; where she moves, what she interacts with. Some of these decisions will trigger QTE sequences – sequences where button presses will only change the outcome of the plot, not create failure for the player – hence removing the common frustration found with random QTE. Even if your character dies, the story will continue without them (this is what I gather from previews.)

Heavy Rain certainly has interactive movie elements, but it would be wrong to define it as such.

edit: Just to explain. What we see in the trailer with the icons coming up is not really QTE as such. In that action scene (which isn’t like the rest of the game where you control the characters movements and interact with NPC’s and solve puzzles etc.) you can look to things in the room to interact with. Ie. you can look to the lamp to wack that over the guys head, or look to the phone to call the police, or look to the stairs to try and run for it. etc.

In an interactive movie there are set videos where you make one decision to start another pre-recorded video to play. Here you control the character and take her where you want to.

Interactive movie – involving button presses – where you won’t fail or “die” if you miss a press, but a different outcome to the events will happen.

Quantic Dreams are extending on what they’ve developed before. And xenovis it’s not a pre-rendered movie, it’s real-time rendered and should display impressive facial animation/graphics. It’s not all from this view, or QTE events. You control the character(s), where she moves and what she does – so really everything that happens is upto you.
