Kate Winslet has won numerous awards including an Oscar as well as widespread critical acclaim in her 20-year acting career but the “Titanic” star admits that she does not always think she has done the best she can on screen. She says, “There are bits of the film I was watching and thinking I could have done that better but I think all actors feel like that, which is a good thing because then you’re constantly trying new things, trying to get better all the time and learn new things too.”
