Director Tim Hill discusses “War with Grandpa”

There’s a John Hughes quality to it I suppose.  It’s a fun movie for everybody with some deeper meaning. It doesn’t pander to kids, and it doesn’t go above their heads.

Producer Rosa Peart discusses “War with Grandpa”

This is a movie for the whole family—Grandma, Grandpa, parents, kids. You don’t have to worry about covering your kid’s eyes. You can just sit back and enjoy.
