" 2015
New Orleans Mardi Gras parade In the late 1980s, Richter attended the
University of Illinois Urbana–Champaign and
Columbia College Chicago as a film major. While at Columbia, he learned the basics of comedic acting and writing by starring in numerous student films and videos. After leaving Columbia in 1988, Richter worked as a
production assistant on commercial shoots in
Chicago. In 1989, he began taking classes at Chicago's
Improv Olympic. He went from student to "House Performer" within a year. Richter branched out working with "The Comedy Underground" and the
Annoyance Theatre. Richter wrote for the short-lived
Jonathan Brandmeier television show. In the early 1990s, the Annoyance Theatre hit gold when producer
Joey Soloway staged
The Real Live Brady Bunch with live, word-for-word performances of the '70s sitcom. The show was so popular that it attracted national attention and moved to
New York City. Richter was not an original member of the cast but the actor who played "
Mike Brady" in the Chicago cast opted not to go to New York. Richter asked Soloway if he could play "Mike" in New York and, since Soloway had not cast a replacement, they agreed.
''Late Night with Conan O'Brien'' At the same time
The Real Live Brady Bunch was playing in New York, two fellow Annoyance members (
Beth Cahill and
Melanie Hutsell, who played Marcia and Jan Brady in the "Real Live Brady Bunch" stage show) were hired as cast members on
Saturday Night Live. With friends on
SNL, Richter attended after-show parties, where he met
SNL writer
Robert Smigel. Two years later, Smigel hired Richter as a writer for a new show he was producing, ''
Late Night with Conan O'Brien''. Smigel sent Richter to join
Conan O'Brien on stage during a practice run-through when the production staff was testing lighting angles and sound, and noticed the two had a strong rapport. He became O'Brien's
sidekick just weeks before the show began airing in 1993. Richter departed from
Late Night after the show on May 26, 2000. He later said of the decision, "After seven years of being on the show, I got itchy. I have a philosophy that if you enjoy good fortune, rather than sit there and say, ‘Oh, that's fine, this amount is good enough for me,’ you should try and push it. You should see how much you can stretch your good fortune. And I was curious."
After Late Night Richter left his post at
Late Night in 2000 to pursue a career acting in films and television. His first major venture,
Fox's
Andy Richter Controls the Universe, was canceled after two mid-season runs. His next Fox sitcom,
Quintuplets, lasted one season. His 2007 television series,
Andy Barker P.I., was co-written and executive produced by
Conan O'Brien. In the series, Richter played an accountant who could not attract clients. After a woman comes to his office thinking he is the former tenant, a private investigator, she asks him to find her husband, who she thinks faked his death. Barker decides to pursue this job and becomes a private detective in earnest, and continues to do his accounting job, which seems to pick up as the series goes on. The series aired on NBC, with all six episodes in the first season on NBC.com. The series was canceled after very poor ratings, despite being named by
Entertainment Weekly as one of the Top Ten Shows of 2007.
The Tonight Show On February 24, 2009, it was announced that Richter would rejoin O'Brien as the announcer for ''
The Tonight Show with Conan O'Brien'' in
Los Angeles. Richter frequently appeared in comedy sketches on the show and often commented and interacted with Conan during the opening monologue; he was also part of the show's writing staff. In mid-December 2009, Richter also began joining Conan on the couch during the celebrity interviews, much like he did in his former sidekick role on
Late Night. Richter said he enjoyed having a steady paycheck again and not having to deal with production companies while developing television shows. Richter said, "Now I'm so happy to be back and making TV every night, not asking permission from somebody and waiting six months to get their sparklingly clear and cogent notes. And then wait another month for them to get back from Hawaii and say, 'Yes, now we can go make television.' I felt like a plumber who kept going into the building and saying, 'Can we put some pipes together?' and watching my wrenches gather dust."
The Three Questions with Andy Richter Since June 2019, Richter has hosted his own
