Scorcese hasn't worked with Schraeder since the excellent Bringing out the Dead cause PS said MS wanted a writers credit and told him to get effed.
In case anyone doesn't know, getting a writing credit provides people an income for the rest of their lives.
Suge Knight dangled Vanilla Ice off the balcony of a high rise hotel to force him to provide a writing credit on "Ice Ice Baby," and by doing so, he discarded millions of dollars in royalties over his lifetime. Probably a wise choice since his life wouldn't have been long if Suge had dropped him out a window.
