We've heard the story about the pageant mom who forced her 3-year-old into high heels; the stage mother who hissed at her pint-sized protege from backstage; the nail-obsessed matron who all but clipped her ballerina's wings.
But what about the porn star dad who got his famous daughter fired from an off-Broadway production for allegedly harassing her co-star?
In what could be a case of fatherly love gone too far, Thora Birch had her stage dreams dashed after she was axed from an off-Broadway revival of "Dracula" a few weeks before its Jan. 5, 2011 opening. Why? According to Paul Alexander, "Dracula's" director, he removed her from the production after her father/manager, Jack Birch, threatened another actor.
Alexander told ABCNews.com that Jack Birch objected to another actor rubbing Thora Birch's back during a scene. When the actor (who Alexander declined to name) tried to explain that he had been directed to rub Thora Birch's back by Alexander, her father said, "Listen, man, I'm trying to make this easier on you – don't touch her."
Alexander interpreted that as a threat.
"Have you seen this guy? He looks a little bit like Freddy Krueger with sunglasses -- which he never takes off, by the way," Alexander said. "So you've got this dude who looks like a body builder standing there on stage saying 'I'm trying to make this easy on you' – how else do you interpret that?"
After meeting with "Dracula's" producers on Friday, Alexander decided to remove Thora Birch from the show and replace her with an understudy.
"I had to let her go for the safety of my cast and crew," he said. "It's unfortunate because Thora's performance would have been an extremely interesting and innovative performance to watch – that's why I hired her in the first place."
Jack Birch denied that he made a threat, telling the New York Times in a story published Tuesday that he was merely "trying to convey Thora's discomfort." Meanwhile, the actress told the Times that she's in a "state of shock" over her firing, but she's not mad at her father: "My dad is my support, and he is the best support that I could ever have."
Neither Jack Birch nor Thora Birch immediately responded to ABCNews.com's calls for comment.
Jack Birch, 62, has appeared in a variety of pornographic films and serves as a manager to Thora Birch, 28. He is married to Carol Conners, who is also an adult film star. Conners and Jack Birch reportedly met on the set of the 1972 adult film "Deep Throat."
Alexander noted that Jack Birch has been a fixture on many of Thora Birch's sets. In 2007, The New York Post reported that he attended Thora Birch's taping of a sex scene for the movie "The Winter of Frozen Dreams."
According to Alexander, Jack Birch's behavior on the set of "Dracula" was similarly intrusive. He said that during a recent rehearsal, one of his producers stopped mid-scene to ask, "Is that Jack peering through one of the set windows?"
"It really was like 'Nightmare on Elm Street,'" Alexander said. "It was bizarre. He also insisted on hanging out in the girls' dressing room. And all the girls are in it. Including other people besides his daughter! I just thought, 'This is getting stranger and stranger.'"
"I have a 31-year-old daughter and it would never occur to me to be that involved in my daughter's life," he added. "It seemed to be exactly the opposite for them."
