Del Close was the driving force behind improvisational comedy in Chicago for over 30 years influencing Bill Murray, Tina Fey, Mike Myers, John Belushi, Chris Farley and the Upright Citizens Brigade to name a few.

After Del's passing in 1999, the UCB started the Del Close Marathon to celebrate their mentor and keep alive his name and teachings for future generations.

From Friday afternoon June 27 to after midnight Sunday June 29, the UCB Theatre in NYC hosts a long-form improv marathon.

Groups from all over the country and world will come to NY to honor Del Close, the legendary improv director and teacher.

There will be over 390 shows spread out on at least five stages.

Shows will range from long-standing improv institutions to absolutely insane late-night shows.
