The Warner Bros. division is developing a sequel of sorts to the 1983 comedy classic, with David Dobkin attached to produce and possibly direct. New Line is meeting with writers to develop the script focusing on Rusty Griswold, the son of Clark Griswold, now a father in his own right who decides to follow the family tradition and take his family on a road trip vacation. The studio is hoping that Chevy Chase and Beverly D’Angelo, who played the parents in the original movies, will make appearances as grandparents, providing a sense of continuity, though no deals are in place.

National Lampoon is not involved at this stage, as Warner Bros. controls the characters and the title. New Line is taking meetings with writers this week, hoping to make a movie that skews more towards Planes Trains and Automobiles or Little Miss Sunshine.
