Tea Leoni is going to be having some "Fun With Dick and Jane." The actress is in negotiations to take the place of Cameron Diaz, who had originally been cast in the Columbia Pictures project but is now stepping aside because of a scheduling conflict arising from a change of dates. Leoni will play the role of Jane in the remake of the 1977 comedy, which has been updated to revolve around a spokesman for a big company who finds himself jobless and an outcast following some dodgy extracurricular activities. In the original film, Jane Fonda and George Segal played an upper-middle-class couple that turned to pulling heists to pay their bills. Brian Grazer is producing for Imagine Entertainment. Leoni recently completed "Spanglish" for Columbia and director James L. Brooks. Her credits include "House of D," in which she co-starred with husband David Duchovny. Leoni is repped by UTA, Mosaic Media and attorney Barry Hirsch.
