LOS ANGELES (Reuters) - Director Paul Thomas Anderson calls his movie ?Phantom Thread? a romance, but its star Daniel Day-Lewis said that filming it made him so sad he decided to quit acting. Triple Oscar winner Day-Lewis plays fastidious 1950s London fashion designer Reynolds Woodcock whose self-centered life is disrupted when his latest muse, Alma (played by newcomer Vicky Krieps), falls in love with him and matters take an unexpected and sinister twist. The kind of things we talked about are the classic gothic romances like ?Rebecca,? ?Gaslight? and ?Vertigo?,? Anderson said.
