Considering the length of time that Pat Carroll played the banjo during the movie, I don't think she would have to fake it. With someone there to show her what to do and about ten minutes' practice, anyone could have managed it.

"It's all in the pickin'" she says, and launches into it. "Bump-diddy, bump-diddy, bump-diddy--" CUT! That's about all. No faking necessary.

Maybe I'm weird, but I liked Songcatcher! I thought it was pretty well done, and with movies, I'm not that easy to please.
