Richter has signed on to star in a comedy pilot for NBC called "Andy Barker P.I.," in which he plays an accountant who somewhat reluctantly is drawn into the world of private investigations.
O'Brien co-wrote the script with former "Late Night" head writer Jonathan Groff after musing about the idea for a year or so, the showbiz trade papers report. The two will executive produce the project with Jeff Ross and David Kissinger of O'Brien's production company, Conaco.
In "Andy Barker," Richter will play an accountant who takes over the office that used to belong to a private eye. Business is slow, until he starts taking on clients looking for the P.I. who formerly occupied the space. Richter agreed to play the part early on in the development process, and Groff and O'Brien tailored the character to him.
Amy Farrington ("The Michael Richards Show") has also signed on to the pilot, playing Andy's wife.
Richter's recent TV credits include starring roles in "Quintuplets" and "Andy Richter Controls the Universe," both on FOX, as well as guest appearances on "Will & Grace" and "Arrested Development." He co-stars in the Will Ferrell NASCAR comedy "Talladega Nights," due in theaters this summer.
He was O'Brien's sidekick on "Late Night" from 1993-2000.
