His TV career began in the mid-1990s working as an editor on Canadian children's shows like
Popular Mechanics for Kids and
Mystery Hunters. He started directing in 2002 on
Mystery Hunters and continued with children's shows such as
Prank Patrol, usually editing his own work. He also edited
Great Hotels,
Passport to Europe and other travel-oriented shows for the
Travel Channel in the early 2000s. In 2007, together with partners
Alex Boylan and
Burton Roberts, Luka launched
Around the World For Free and set off on a trip around the globe, from September 18 to February 23, 2008. Luka directed, filmed and edited the online series on the fly (once, in a butcher shop with newly slaughtered pigs hanging behind him), producing eight hours of edited content for the online audience. The program had a loyal following that even included schoolchildren, who welcomed the travelers back at the end of the journey during a visit to their school. The online project was re-packaged for television by Luka and sold to
WGN America who began broadcasting in spring 2009. Luka undertook a smaller online/broadcast hybrid project mirrored on the same model for
Rachael Ray in the summer of 2008 called
Rach to the Rescue. On July 26, 2010, Luka reprised his role of producing, directing and editing the second season of
Around the World For Free, this time for CBS.com, with new host Jeff Schroeder of
Big Brother 11 and
The Amazing Race 16 fame, and major sponsors
AT&T and
American Airlines attached. They set off from
The Early Show on a 105-day journey around the world, with Luka filing popular webisodes (over 7 million video streams and 4 million page views ) from thirteen countries visited. Only one week after wrapping the show on November 4, 2010,
Around the World For Free won both "Best Video Series/Show" and also "Best of Show" at the inaugural Diva Awards in New York City. Luka's charity efforts include in-kind donated videos for organizations such as the
Cambodian Red Cross. ==Awards/nominations==
