Overacting is a self-indulgence, while underacting comes either through a lack of talent or a lack of courage.
Interpretation
The quote suggests that overacting is a form of self-indulgence, whereas underacting can stem from either insufficient talent or bravery.
Gregory Peck's quote reflects on the fine balance required in acting. He posits that overacting is often a result of an actor's desire to draw attention to themselves, indulging in their own performances rather than serving the story. On the other hand, underacting might signify either a deficiency in skill or a fear of fully immersing oneself in the character, representing a lack of confidence to fully express emotions and engage the audience.
In practice
Discussing acting techniques in a drama class.
There is no doubt that the princess did become a queen---not only on the screen. One of the most loved, one of the most skillful, one of the most intelligent, one of the most sensitive, charming actresses---and friends, in my life---but also in the later stages of her life, the UNICEF ambassador to the children of the world. The generosity, sensitivity, the nobility of her service to the children of the world and the mothers of the world will never be forgotten.
Whatever's merely willful, and not miraculous (be never it so skilful) must wither fail and cease - but better than to grow beauty knows no.
If you're actually allowing your creative part to control your writing rather than a more commercial instinct or motive, then you'll find that all sorts of interesting things will bubble up to the surface.
The writing gets done away from the keyboard and away from the studio in my head, in solitude. And then I come in and hopefully have something, then I wrestle with sounds and picture all day long. But the ideas usually come from a more obscure place, like a conversation with a director, a still somebody shows you, or whatever.
I have a deep-seated distrust and even contempt for people who are driven by ambition to conquer the world … those who cannot control themselves and produce vast amounts of crap that no one cares about. I find it unattractive. I like the Zen artists: they’d do some work, and then they’d stop for a while.
Writers should provoke disagreement.
The writer is both a sadist and a masochist. We create people we love, and then we torture them. The more we love them, and the more cleverly we torture them along the lines of their greatest vulnerability and fear, the better the story. Sometimes we try to protect them from getting booboos that are too big. Don’t. This is your protagonist, not your kid.
