When she was a teen, kids used to call Winslet "Blubber" because she was chunky. Her weight has fluctuated since she blew up (in terms of fame) in Titanic but she's never lost perspective and starved herself. One, we appreciate the thickness. Two, we take it to mean she cares about what's on the inside, which is good because that's where we can be found during the winter, when our exercise routine consists mostly of getting dome.
Winslet is drawn to the role of sexual deviant, having played an adulteress (Little Children), a statutory rapist (The Reader) and a seductive corpse that gives Joaquin Phoenix a stiff one (Quills). Now that's just dead wrong.
