I’m not famous for my back story investigations I’m lucky that I work with good writers and it’s usually in the script.

Nighy is describing a pragmatic approach to acting: rather than constructing elaborate off-screen biographies for his characters, he relies on what the screenplay already provides and on collaboration with strong writers. The remark implicitly pushes back against a certain kind of “method” mythology, suggesting that performance can be built from close reading, craft, and responsiveness to the text. It also credits writers as primary architects of character, positioning the actor as an interpreter who brings nuance to what is on the page. The tone—self-deprecating and appreciative—frames this as preference and good fortune rather than a rigid doctrine.
