Well, in Bogdanovich's case, he does at least have a valid claim, as he gave Welles money for the film (I think somebody on the board recently mentioned $200,000...a rough inflation adjustment, off the top of my head, would come out to around $800,000 nowadays). And it would be wise for him to ask for it up-front, since Welles' films have always been shaky commercial prospects (at best). As for BWS, the only reason that I can see anybody paying her money is to get her to shut the hell up and go away (no, wait, she needs the money for her animal shelter, I keep forgetting...not to sound insensitive or anything, but does she think that people gave her father money just because of who he was? I mean, he did have to do something for it). Not that Oja is really much better in this case: really, did she put her own money into the film like Bogdanovich did? Did she give Welles a place to live like Bogdanovich did? Has she done anything substantial in the past 40 years?
You're right, Hadji, there is a lot of greed involved with this...and the funny thing is, there's greed over something that isn't even guaranteed to recoup its costs!
