I saw a movie a couple years back where the actress played a cellist. OMGosh! They could have trained her how to sit and hold a cello and bow. How to act at least to look like she is playing, and feel comfortable in the distant shots. Then, in the closeups where you can't see her face, they should have had an actual cellist do it. It has been done in other movies in closeup shots. I mean, really? She was playing upper register shifting A string notes on the C string! Really? That was so obvious because it was a solo part. Nope. They had her doing the closeups, too. The bowing was way over the fingerboard and pointing right up to the sky, in most shots. Didn't actors used to prepare for their roles? Get into character? It was terrible. Ruined the entire movie. I love older movies. 

I wish I could remember the name of the movie and cast, but I can't. I just happened across it, I was not looking for it. It was not a comedy, but sure looked like one. A couple people should not get another directing and producing job. 

On an up note. The cello itself was beautiful! The prop master did. good job finding that cello. Look for the bright spot.

So hearing about a movie where this was not the case, is bright spot 2.
