Brian Cutler highlights the difference between simply watching a scene partner and truly seeing them, a depth of awareness that enhances on-screen connection. He recounts an example from class, where a student missed an emotional cue, illustrating the importance of genuine perception in acting. Comparing this awareness to the sonar-like sensitivity of dolphins, Cutler emphasizes that actors must deeply connect with their partners, picking up on subtle emotional cues to create authentic, powerful scenes.
