Most actors play a part of their own personality. Daniel Day-Lewis always inhabits another.

Look at “Phantom Thread” and you’ll understand why he takes so long to agree to a role.

As Reynolds Woodcock, a fashion designer, he’s meticulously detailed, revealing the mechanics that go into the creator’s work. Day-Lewis sketches with purpose, sews with heart and preps with precision.

It’s fascinating to watch his wheels turn – even when the story they’re in isn’t all that compelling.

Set in the 1950s, “Phantom Thread” shows what a controlled life Woodcock lives. He insists on silence at the breakfast table, consistency in his schedule and power in his life.

“I cannot begin my day with a confrontation,” he tells a breakfast partner. Sure enough, she’s gone and his life goes on.

When he meets an intriguing waitress (Vicky Krieps), she becomes a muse and, to some degree, a partner.

His sister (Lesley Manville) knows the relationship will never be equal, particularly since she’s in control of business. She offers a warning, but the waitress presses on and becomes the woman most likely.

Writer/director Paul Thomas Anderson could have settled for a perfect slice-of-life drama but he pushes it even more and shows how truly screwed up Woodcock can be.

“Phantom Thread” takes a surprising turn, then drifts. It’s an interesting choice. But until it happens we get to see the master at work.

Royals ask for his dresses; the wealthy insist on them. When he’s upset with one of his customers’ behavior, he pulls the dress off her and never looks back.

Anderson gives Day-Lewis plenty of moments, never pulling the camera away. To emphasize the man’s elegance, he accompanies each scene with a piano score that can be both vulnerable and forceful.

The costumes are gorgeous; the settings sumptuous.

While the “Pygmalion” underpinnings show through, they can’t hide the thriller that lurks.

When Woodcock becomes annoyed, simple tasks (like buttering toast) become aurally amplified. It’s a neat trick, designed to help us understand what Day-Lewis is creating.

Both Krieps and Manville are good foils, pushing and pulling in opposite directions.

Harriet Sansom Harris adds humor; Brian Gleeson gives “Thread” a tinge of “Masterpiece Theatre.”

The film, though, belongs to Day-Lewis, who makes a control freak utterly interesting. Thanks to his work, it’s an exquisite creation.
