So this movie, August Rush was recently on tv (by recently I mean...an hour ago) and the tv info blurb mentioned a cello so I was definantly hitting it up. It's a about an orphaned boy who uses his love for music to find his family. Usually there's a disappointment after a movie involving musical instruments because more often than not, the actors have never played them. But I was really impressed. The actor who plays the boy, Freddie Highmore (Charlie in Willy Wonka and Peter in Finding Neverland) must have done some serious practicing on the guitar to make it look legit and of course along with a good double.
And of course, a good old guitar slapping in a movie never hurt anyone.
