It's literally just D A Bm G throughout the whole song, I think! It works acoustically. :) D A Bm G x2 
DA Started out like, in the movies
BmG But it ended, like a bad dream
DA Curtain opened, heard the crowd roar
BmG This ones a repeat, seen it before
DABm Rewind to the start before it all went wrong
G Whats going on?
DABm Fast forward to the end, after everyone's gone home
G And they've forgotten it all
DA This ain't a movie that I wanna see
BmG A tragic story, starring you and me
DABm Yell cut we're stuck inside this scene
G This is heartache on the big screen
DA The clock is ticking, and I'm out of time
BmG The camera's rolling, and I've forgot my lines
DABm My script is ripped and now I see
G This is heartache on the big screen
D A Bm
G This is heartache on the big screen
DA Curtain closes, oh that's cliche
BmG Like a story, of a bad day
DA Back to square one, where I started
BmG As I stand here, broken-hearted
DABm Fast forward to the end, after everyone's gone home
G And they've forgotten it all
DA This ain't a movie that I wanna see
BmG A tragic story, starring you and me
DABm Yell cut we're stuck inside this scene
G This is heartache on the big screen
DA The clock is ticking, and I'm out of time
BmG The camera's rolling, and I've forgot my lines
DABm My script is ripped and now I see
G This is heartache on the big screen
DA If Hollywood could see me now
BmG I've got this starring roll
DABmG But they won't so I'll just keep on acting a fool
DA This ain't a movie that I wanna see
BmG A tragic story, starring you and me
DABm Yell cut we're stuck inside this scene
G Yeah!
DA The clock is ticking, and I'm out of time
BmG The camera's rolling, and I've forgot my lines
DABm My script is ripped and now I see
G This is heartache on the big screen
D A Bm
G This is heartache on the big screen
D A Bm
G This is heartache on the big screen
