As Welles' fans, I think there's an impulse to take away credit from directors in films that O.W. has acted in and give it to Welles. Anything good in the film is because of Welles. Anything unsuccesful is because of the director of record.
I know Welles did take part in the look of Journey and is credited as an uncredited director on Black Magic.
Welles did "design" the opening shot of Journey. And did help in the final chase on the side of the building. But according to Welles, he wasn't on the set in scenes he didn't act in. He adds that everyone helped direct the final chase scene.
For Black Magic. He was working on Ambersons during the day and acting at night on Black Magic.
Welles has said time and time again that Norman Foster deserved the credit for Journey.
And that Carol Reed solely directed Third Man.
Yes, we can see his influence on these films and many others. But to give him too much credit simply diluted the actual work that Welles did do.
