The Pushing Daisies Emmy victor replaces John Lithgow, who played the hapless killer Larry Henderson in the freshman run of the show.
The season two premiere date is not yet known.
What do you think about Kristin Chenoweth joining Trial & Error season 2, and are you still hoping for some more Easter on American Gods?
Nicholas D'Agosto, Jayma Mays, Steven Boyer and Sherri Shepherd, who appeared in season one, will return.
Chenoweth will take on the role of Lavinia Peck-Foster, who is described as the first lady of East Peck who is a larger-than-life grand dame - at least in her own mind. What happened? Her husband Edgar's body is discovered stuff in a suitcase in the back of her auto.
She will portray Lavinia Peck-Foster, an eccentric heiress accused of murdering her husband after she is found with him stuffed in a suitcase.
"We are delighted to have such a comedic powerhouse join our show", said Trial and Error executive producer and creator Jeff Astrof in a statement. "I admire John Lithgow so much and want to make him proud by continuing what he began", Kristin said in a statement. "When we decided we were doing a murderess, we knew there could be only one person big enough to fill John Lithgow's skates".
On the TV side, Chenoweth won an Emmy for her role on Pushing Daisies and was nominated for her guest-starring stint on Glee.
However, we do wonder what this means in terms of her availability for the second season of American Gods, which recently found a showrunner. On Broadway, Chenoweth received a Tony for her performance in You're a Good Man, Charlie Brown. She was also nominated for both her iconic original role as Glinda the Good Witch in "Wicked" and for playing Lily Garland/Mildred Plotka in "On the Twentieth Century".
Astrof and Matt Miller serve as writers and executive producers for "Trial & Error". The series is produced by Other Show Productions and Good Session Productions in association with Warner Bros.
