Robbie Thompson reading to us exactly what he wrote in the script for ‘Baby’:

R: “The song kicks in and we move through quick shots of the
boys singing along, laughing, talking, eating fast food. New paragraph…”

R: “Being brothers.”
And then that’s it, that’s all I wrote. So everything you see there is
them, and the director said ‘let’s just give
them room to play.’

L: Wait, so Jared changed the line to ‘in my brother’s 67
Chevy’?

R: Yeah, that’s all Jared.
