But Then ...
She has appeared in virtually nothing of note since 2001. And the cause appears to be her ex-porn star father.
Yes, Jack Birch was a 1970s porn star, most famous for appearing in Deep Throat. He functions as Thora's manager, although not a very good one, since all he seems to do is cause trouble and get her fired.
Jack's background might help explain his rather bizarre behavior, particularly when it involves his daughter's body. For instance, during the filming of Winter of Frozen Dreams, Jack insisted on being present for her adult scenes. Now, this was understandable with American Beauty, because she was underage and parental supervision was required for anything involving nudity. But she was now 26, and Dad was still hanging around, giving the crew instructions on how to make his baby girl look like a good lay.
He even threatened to pull her off the movie and kill the assistant directors because they weren't shooting the sex scenes the way he wanted. At one point, he gave the actor playing Thora's lover a "thumbs up," while he was having sex with her.
