Year of the Dog star Laura Dern appeared on The Ellen DeGeneres Show yesterday and talked about her 5 1/2-year-old son Ellery Walker‘s newestobsession – dinosaurs – and his recent epiphany to which shehas a connection.

Laura says she didn’t know how to inform her son that she stars in thefilms, but eventually eased into it, which only peaked Ellery’sinterest. However, afterconsulting with Steven Spielberg, Laura decided to hold off on it.

Laura and husband Ben Harper also have a daughter, Jaya, 2.
