There’s a long and very informative Q&A today by PR.com’s Allison Kugel with singer Nancy Sinatra. The conversation covers everything from the famous daughter’s early World Wide Web fan interaction efforts in partnership with dad to her blunt assessment of getting a star on the Hollywood Walk of Fame.

Sinatra also confirms she’s been part of the meetings process with Martin Scorsese about the long-rumored Hollywood biopic of Frank, and that at this point it’s still all about the script. She then shares a tantalizing casting suggestion:

Personally, I think Simon Baker (The Mentalist) could do it. But I’m not involved in the casting. I see his smiling and his twinkling eyes and I see my dad. I don’t think anybody’s ever mentioned him and I certainly haven’t mentioned him to my sister or to Marty [Scorsese], and I wouldn’t because that’s not my job… but in a meeting I might.

It’s an inspired idea. As Jamie Foxx showed with 2004′s Ray, musical biopics are first and foremost about on-screen charisma, not the pipes. Overdubbed with Sinatra’s sound recordings, young Tasmanian green eyes could very well do the Sinatra honors.
