Milla Jovovich wept with joy when she landed the lead in “Stone” with Robert De Niro and Edward Norton. “I cried when they told me I’d got it. I was so happy that I was able to share more with these two icons,” Jovovich said at Tuesday’s premiere. Best known for her action roles, she craved the part in the psychological thriller: “You don’t get scripts like this every day. I get to do my little comedies, my big action films, but this movie is very special . . . There were quite a few days on set that I wouldn’t bring my baby and I’d come home in tears, it was so intense.”
