Going topless on screen can make or break you. Regardless, the images are everlasting. Halle Berry, for example.
From Starpulse: "[Halle] Berry's long-awaited first topless scene came in crime thriller Swordfish, in a shot of glory that millions of fans waited for. The actress is seen sunbathing topless and reading a book, which blocks her breasts from view. She then moves the book for a short conversation, exposing herself on celluloid for the first time."
