I was just reading the notes to "The Cradle Will Rock" script, and had forgotten that OW intended for it to be a black and white film; suddenly I recalled that he also intended to make both "Big Brass Ring" and "King Lear" in black and white also. This means that his colour period was about a decade long, from "Immortal Story" in 1966 to the probable release of "The Other Side of the Wind" and "The Dreamers" in the late 70s, had he gotten the financing to complete them. But "Brass", "Cradle" and "Lear" would have been B&W.
I've always felt that Welles was stronger in B&W, that he lost a lot of power in colour... and of course he was with the trend at the time, as Woody released "Manhattan" in beautiful B&W in 1979, and Scorcese released "Raging Bull" also in B&W in 1980. So I don't think anyone would have had a problem with OW releasing his pictures in that form at that time.
Just another thought...
