Dean Jagger won an Oscar from his only nomination for portraying Major Harvey Stovall in Twelve O'clock High.
Jagger simply has a distinct lack of screen presence, even though I was watching the film for him, at times I would barely even notice he is in a scene due to his lack of charisma as a performer. Jagger, even when a scene centers on him, never creates a memorable characterization of Stovall. Stovall becomes just almost a functional character, because Jagger fails to really realize him in his performance.
Jagger stays rather dull and uninteresting throughout his portrayal, but hey he is even given a drunk scene. Jagger in his drunk scene is pretty bad actually. He frankly just did not seem to be drunk, or even acting drunk, he just was incredibly poor in this scene. In fact this scene was suppose to be quite a poignant moment, but Jagger was unable to bring any really depth to his performance, or even competence causing the utter failure of this scene. Overall Jagger does have, I think, a good character, but Jagger fails to make anything out of what he is given. I do believe another better actor in this role could have made the character of Harvey Stovall really shine.
