Based on the provided image, here's a detailed breakdown of the observed facial and body expressions, and the possible emotions they might convey:

1. **Eyes**: 
   - **Widened eyes**: This often indicates shock, surprise, or fear. The whites of the eyes are highly visible.
   - **Furrowed brows**: This shows deep concentration, concern, or distress.
   - **Tensed upper eyelids**: Indicates a heightened state of alertness.

2. **Mouth**: 
   - **Open mouth**: Expresses shock or disbelief.
   - **Lowered corners of the mouth**: This suggests sadness or displeasure.

3. **Nose**:
   - **Flared nostrils**: Indicate heightened arousal, anger, or agitation.

4. **Forehead**:
   - **Deep vertical lines**: Indicate intense concentration or deep thought, possibly combined with stress or concern.

5. **Overall Face**:
   - **Tensed facial muscles**: Convey intensity, stress, or a heightened emotional state.
   
6. **Body Language** (limited view but based on visible parts):
   - **Neck tendons visible**: Indicates intense strain or shouting.

From the combination of these expressions, the primary emotions seem to be distress, shock, disbelief, and possibly fear. The intensity of the displayed emotions, combined with the tensed facial muscles and neck tendons, suggests a situation of extreme emotional upheaval.

Considering the authenticity of the displayed emotions:
The expressions appear genuine due to the combination of several congruent facial signals. For instance, it's challenging to fake both widened eyes with furrowed brows and flared nostrils simultaneously, as these muscle movements are often involuntary responses to genuine emotions.

However, given that this is an image from a film (Obi-Wan Kenobi from the Star Wars series), the actor's intention is to portray a specific emotion as authentically as possible for the scene. Hence, while the displayed emotion might appear genuine, it's essential to remember that actors train to express emotions on cue.
