Christopher Guest (born February 5, 1948, in New York City) has always had a yen for show business. After attending New York City's High School of Music and Arts, he took a brief respite from the city to attend Bard College before coming back to pay his dues on Broadway -- first in a 1970 revival of "Room Service" and, later, in "Moonchildren."But even then, he was already honing his sharp skills at comedy writing, penning articles for National Lampoon. After acting in a Rob Reiner made-for-TV movie, Guest teamed up with the director once again to write 1983's This Is Spinal Tap, in which he played the vapid rocker Nigel Tufnel.An accomplished filmmaker, Guest (who's married to Jamie Lee Curtis) is to offbeat mockumentaries as Alfred Hitchcock is to horror movies, helming such cult hits as Waiting for Guffman, Best in Show and A Mighty Wind.
