This is my first tab or w/e so I know it sucks a lot, this song literally came out 
4 days ago and I've figured this out by listening to live videos only.
It's literally just D A Bm G throughout the whole song, I think! It works acoustically. :)

//CAPO 1//

[INTRO] D A Bm G x2


[VERSE ONE]
D                        A
Started out like, in the movies
       Bm             G
But it ended, like a bad dream
        D                 A
Curtain opened, heard the crowd roar
            Bm              G
This ones a repeat, seen it before


[PRE-CHORUS]
D             A                        Bm
Rewind to the start before it all went wrong
            G
Whats going on?

D                   A                     Bm
Fast forward to the end, after everyone's gone home
G
And they've forgotten it all


[CHORUS]                      
D                      A            
This ain't a movie that I wanna see
Bm              G
A tragic story, starring you and me
D              A                 Bm
Yell cut we're stuck inside this scene
        G
This is heartache on the big screen
D                         A
The clock is ticking, and I'm out of time
Bm                        G
The camera's rolling, and I've forgot my lines
D            A                Bm
My script is ripped and now I see
        G
This is heartache on the big screen


[INTERLUDE] D A Bm
        G
This is heartache on the big screen


[VERSE TWO]
        D                 A
Curtain closes, oh that's cliche
       Bm          G
Like a story, of a bad day
        D                   A
Back to square one, where I started
     Bm                 G
As I stand here, broken-hearted


[PRE-CHORUS]
D                   A                     Bm
Fast forward to the end, after everyone's gone home
G
And they've forgotten it all


[CHORUS]                      
D                      A            
This ain't a movie that I wanna see
Bm              G
A tragic story, starring you and me
D              A                 Bm
Yell cut we're stuck inside this scene
        G
This is heartache on the big screen
D                         A
The clock is ticking, and I'm out of time
Bm                        G
The camera's rolling, and I've forgot my lines
D            A                Bm
My script is ripped and now I see
        G
This is heartache on the big screen


[BRIDGE] (i'm not sure about this)
   D               A
If Hollywood could see me now
Bm            G
I've got this starring roll
D                 A                 Bm       G
But they won't so I'll just keep on acting a fool


[CHORUS]
D                      A            
This ain't a movie that I wanna see
Bm              G
A tragic story, starring you and me
D              A                 Bm
Yell cut we're stuck inside this scene
G
Yeah!
D                         A
The clock is ticking, and I'm out of time
Bm                        G
The camera's rolling, and I've forgot my lines
D            A                Bm
My script is ripped and now I see
        G
