Steven Long Mitchell has worked in an almost exclusive partnership with fellow TV writer-producer Craig W. Van Sickle. After getting their start in the 1980s with episodes of the guest-star-highlighting sitcom "The Love Boat" and the amateur-detective mystery series "Murder, She Wrote," Mitchell and Van Sickle saw their first extended gig in the form of the sci-fi fable "Alien Nation," a 1989-1990 series for which the pair penned five episodes. Shortly thereafter, they created their first series in "Cobra," a syndicated action-adventure about a fugitive ex-Navy Seal starting a new life with an undercover agency after a hostile run-in left him with a reconstructed face. The duo expanded on their themes of identity and intrigue with the follow-up project "The Pretender" (1996-2000), in which the title character effortlessly slips into various personalities at the behest of the mysterious Centre organization. After the NBC series connected with a significantly larger audience than their previous venture, the network tapped Mitchell and Van Wickle for the female-centric series "She Spies," allowing the writing team to inject their brand of espionage with a healthy dose of humor. In addition to contributing several scripts to such government procedurals as "NCIS" and "Medical Investigation," Mitchell and Van Sickle famously re-imagined the classic "The Wizard of Oz" as the highly rated 2007 miniseries "Tin Man."
