Acting

Letscher got his first professional acting job with a role in The Tropic Pickle, during the second season of Jeff Daniels' Purple Rose Theatre Company in Chelsea, Michigan. Letscher impressed Daniels enough that the veteran arranged a meeting for Letscher with Ron Maxwell, the director of Gettysburg. After appearing in a small role, Letscher took advice from Daniels and moved to Los Angeles. He quickly found work in guest roles on television.^[2]

In 1995, Letscher was cast as the naive television writer in the Nancy Travis sitcom Almost Perfect, which lasted for a season and a half. He went on to appear as series regular in Living in Captivity in 1998. The same year, he appeared in the film The Mask of Zorro as the villain Captain Harrison Love. He appeared in the miniseries Jackie, Ethel, Joan: Women of Camelot and in the television films King of Texas, The Beach Boys: An American Family, When Billie Beat Bobby, and Stolen Innocence. He also reunited with Daniels in Gods and Generals (the prequel of Gettysburg) and Daniels' directorial effort Super Sucker. Letscher also returned to The Purple Rose Theatre in the world premiere of Landford Wilson's play Rain Dance.

In 2002, the comedy pilot Good Morning, Miami was picked up by NBC as part of Must See TV Thursday comedy block, but Burke Moses was replaced by Letscher and a second pilot had to be filmed. The romantic comedy sitcom featured Letscher as a smarmy former network anchor who was the primary romantic rival to main character Jake Silver (Mark Feuerstein) for the affection of Dylan (Ashley Williams).^[3] Despite the series receiving negative reviews, Letscher and Constance Zimmer were standouts in the series and eventually paired up as a combative couple. But the show was canceled midway though its second season due to low ratings.

His performance in Good Morning, Miami led to him being cast in the lead in the film Straight-Jacket, opposite Carrie Preston, about a gay Hollywood actor forced to marry a beard in the 1950s.^[4] His flair for classical farce also led to him being cast in the leading role of Capt. Jack Absolute in the Lincoln Center theater production of Richard Brinsley Sheridan's The Rivals. Letscher was praised for his spirited performance and his costar Robert Easton referred to Letscher as "a perfect classical actor."^[2]

Letscher was in the cast of Joey, and had a recurring role on The New Adventures of Old Christine and numerous guest starring roles. After appearing as a kind neighbor in Alan Ball's Towelhead, Letscher was cast in Eli Stone, as Nathan Stone, the prophet's kind-hearted older brother. Despite low ratings, the dramedy series had loyal fans and critical acclaim, earning it a second season which included a larger role for Letscher. His work on Greg Berlanti's Eli Stone lead to his arc on Berlanti's Brothers & Sisters as a love interest for the married Kitty Walker.

In 2012, Letscher starred in the series Bent and Scandal, and was cast in the series The Carrie Diaries as Tom Bradshaw, Carrie Bradshaw's widowed father.^[5][6] The show ran for two seasons from 2013 until 2014.^[7] He appeared in the 2013 films, Atom Egoyan's Devil's Knot (about The West Memphis Three) and Spike Jonze's comedy Her, opposite Amy Adams.^[8] Letscher portrayed Eobard Thawne / Reverse-Flash, initially in a recurring role on The Flash and later as a regular in season two of Legends of Tomorrow,^[9] and reprised the role in two episodes of its seventh season.^[10]

Writing

In June 2007, Jeff Daniels' Purple Rose Theatre Company in Chelsea, Michigan, staged the world premiere of Letscher's original play Sea of Fools, a farce set in Joseph McCarthy-era Hollywood. Film director Elia Kazan is a character in the play. Daniels initially planned to direct the play but pulled out, allowing Letscher to also direct the play.

In 2009, his play Gaps in the Fossil Record was staged at the Pacific Resident Theater, then had its world premiere production at the Purple Rose Theatre in 2016.^[11]
