Final answer:
The fuel that drives acting is the emotional and physical investment of the actor, which is essential for delivering a believable performance. Actors need to tap into their internal realities, reveal vulnerable parts of themselves, and react truthfully to their experiences. Training, conditioning, and developing kinesthetic awareness are important for achieving this.
Step-by-step explanation:
The fuel that drives acting, both individual performance and group performance, is the emotional and physical investment of the actor. In order to deliver a believable performance, actors need to tap into their internal realities, reveal vulnerable parts of themselves, and react truthfully to their experiences. This requires a combination of training, conditioning, and developing a deep kinesthetic awareness.
For example, physical exercises that push actors to their limits can help integrate their body, breath, and intentions. Ultimately, the key is to balance the emotional and physical demands of a performance with the practical challenges of collaboration.
