The search is on for some little "Fockers."  The studio that's making the third "Meet the Parents" film is looking for a boy and a girl to play the son and daughter of Ben Stiller and Teri Polo's characters.  Both kids need to be around 6, 7 or 8.  The boy's character is described as "a little oversensitive and kind."  The girl is a tomboy.  Since kids can only work a little each day, identical twins or triplets could have an advantage.  Filming on the movie, which doesn't have a confirmed title yet, will be in California from July through October.  Casting calls are May 30th in three locations.  Newport Beach and North Hollywood, California, and New York City.  For details, or to send your kid's resume and photo, email: castingfockers@gmail.com
