I think Polanski is a very great director, and he actually has starred in some of his films. He does not have a recognizable shtick like Allen does, playing a lovable shlub. His acting is subtle.
However, unlike Allen, he is not a US citizen, so being “exiled” from the US, and “forced,” so to speak, to work outside of Hollywood, was no sweat for him. Of course, Woody Allen has always worked outside of Hollywood, technically, funding all his projects independently, but my point is that lots of directors who are not American direct films in Europe. It’s not so common for Americans (location films for Hollywood studios don’t count).
It’s a more salient point that Polanski has only partially denied the charges against him (IIRC, he acknowledged “having sex with,” not raping, the victim, and denied that he drugged her or knew she was drugged; I don’t recall whether he knew he age). He agreed to a plea bargain, which (again, IIRC) was rejected by the judge.
Allen has straight ticket denied everything. He even denied having sex with Soon-yi before she was 18. I allow that could be true, because Soon-yi backs it up, albeit, if it turned out to be false, I would not be shocked, but still think it has no bearing on what did or did not happen with Dylan.
It’s also interesting to me that Farrow has never publicly denounced Roman Polanski, and still says working with him was a great experience. And it strikes me as a little creepy that the name she chose for her son, when she wanted to ditch the name Allen had chosen, is so close to “Roman.”
