Art & Science: All in the Family?

David at symmetry breaking points out the question of musicians (by which he means serious musicians, or at least rich/famous ones) with physicist parents. David's got Mark Everett (whom I wrote about a few years ago) and I've noticed a surprising number of well-known creative children with physicist parents, particularly folks in the motion picture (TV & film) industry:

• Kieslowski muse Irene Jacob (Red, Double Life of Veronique), daughter of Maurice Jacob
• Character actor Josh Pais, son of Abraham Pais
• Pirates of the Carribean director Gore Verbinski, son of Vic Verbinski (nuclear physicist at Oak Ridge)
• TV Star Jon Stewart's (nee Liebowitz) estranged father was apparently a physicist

Of course, the begged question is if the rates of talented kids from physicists in any sense exceeds those descended from other professions. Anyone with insight on this? I personally came from a family with deep involvements with the arts (art history majors, sibling with MFA, art collecting, etc.) and I ran as fast as I could to the sciences, so I could imagine the inverse effect (by detailed balance, natch).
