I really like Sage Kirkpatrick in this one

Sage Kirkpatrick as Dr. Holland has some moments that stayed in my mind. The acting feels natural, and I can follow the feeling very easily. The timing is good, and the emotion comes at the right moments. It is not too loud, but I still remembered the performance after watching. I think this work helps the movie a lot, even when the story is busy. There are small expressions that make the character feel more real. I remember both the good parts and the parts that did not work so well.
