The “Saturday Night Live” alum will star opposite Sigourney Weaver and Jennifer Love Hewitt in “Breakers” and will topline with Danny DeVito and Martin Lawrence in “What’s the Worst that Could Happen?” Dunn was last seen in “Three Kings” and “What Planet Are You From?”In laffer “Worst,” she’ll play DeVito’s wife, who can tolerate his philandering, but is devastated when their house is robbed. Pic is being produced by Lawrence Turman, David Hoberman and Wendy Dytman, and will be helmed by Sam Weisman. She will segue to “Worst” from “Breakers,” which will be helmed by David Mirkin and produced by John Davis and Irving Ong.
