Smith played in several
lo-fi experimental bands in New Zealand and released a few albums with Say Yes to Apes and Hyphen-Ears in the mid-1980s. After suffering a
concussion while playing university
rugby union in 1987, Smith was forced to sit on the sidelines for almost three weeks. His wife saw a casting call advertisement for the touring musical tribute to
Elvis Presley,
Are You Lonesome Tonight, and signed up Kevin for an audition. He got the role of bodyguard JoJoe and was the lead understudy. Later that year, Smith joined Christchurch's Court Theatre and performed on stage for the next three years in a variety of roles including Don Pedro in
Shakespeare's Much Ado About Nothing and
Stanley Kowalski in
Tennessee Williams'
A Streetcar Named Desire. In 1989, Smith co-founded a Christchurch
theatresports group,
Scared Scriptless, performing live comedy. Later that year he got the role of charming "bad boy" Demian Vermeer on the New Zealand primetime soap opera
Gloss, and moved to Auckland to work on the series' final season. In 1993, Smith played Lawrence Hayes in
Desperate Remedies. He then appeared as Paul Cosic in the last two seasons of the primetime drama
Marlin Bay. For this role, he won the 1995 New Zealand Film and Television Award for Best Supporting Actor. He screen-tested for the lead role in Paramount's big budget action-film
The Phantom, but the role ultimately went to
Billy Zane instead. His fellow
Hercules: The Legendary Journeys cast member, low-budget-movie actor and Pacific Renaissance Pictures partner
Bruce Campbell, was also one of the contenders for the role of the legendary
superhero. Also in 1995, Smith appeared on
Hercules: The Legendary Journeys as Hercules' half-brother,
Iphicles. Later he joined the cast of
Xena: Warrior Princess as Ares, a role he would later play on
Hercules and
Young Hercules as well. As the dark and dangerously seductive Greek god of war, Smith gained legions of fans. During this time Kevin performed as Ares on
Hercules: The Legendary Journeys,
Xena: Warrior Princess and
Young Hercules simultaneously. While starring on
Xena,
Hercules and
Young Hercules, Smith also appeared in other TV shows and films, notably as a
Vietnam veteran in the feature film
Channelling Baby and as detective John Lawless in three TV movies:
Lawless (1999),
Lawless: Dead Evidence (2000), and
Lawless: Beyond Justice (2001). For the first he was nominated for the
New Zealand Academy of Film and Television Art award for Best Actor. In the
mockumentary Love Mussel (2001) he played himself covering the story of a small town in New Zealand following the discovery that a local shellfish, the
geoduck, has similar effects to
Viagra. Smith also continued to act in the theatre. During his career, he also appeared on several cassettes of alternative music, alongside other musicians, under the band names "The Picnic Boys" and "Say Yes to Apes" which was later renamed "Hyphen-Smythe". He was one of the lead singers of the celebrity band "The Wide Lapels", a band famous for its campy performances of the worst songs of the 1970s. ==Death==
