The comic misadventures of the beleaguered Griswold family continue in this latest "Vacation" outing, the third and most successful of the series. (Over $71,000,000!) This time America's most dedicated dad (Chevy Chase) is determined to stay at home to create "the most fun-filled old fashioned family Christmas ever" -- but life has a particular way of throwing wet logs on Clark Griswold's fire. Look for Emmy and Golden Globe-winner Julia Louis-Dreyfus (TV's "Seinfeld") in a supporting role. Written by John Hughes ("Home Alone" series).
