Zor Ka Jhatka was shot in Argentina with contestants. Anchor Shah Rukh Khan, who is in Mumbai, will be shown as present on sets through use of special effects

Zor Ka Jhatka host Shah Rukh Khan wasn't present in Argentina, where major portions of the reality television show were recently shot.

However, he will appear in several sequences through chroma keying. The star anchor will be incorporated on the Imagine show through use of the technology.

As such, certain segments that have been shot at a studio in Mumbai to depict face-offs with the participants will have his physical presence.

Actress-anchor Soumya Tandon, who shot on location in Argentina will be seen goading contestants to complete physical tests of endurance.

Says a source close to the channel, "Zor Ka Jhatka is a reality competition featuring various obstacle courses that were shot on location in Argentina.

The participants spent considerable time in Buenos Aires, where various international versions (of Wipeout, the original show name) have also been filmed.

Shah Rukh wasn't present on location. However, the chroma key effect will incorporate SRK wherever needed."

However, the channel feels "it is okay for the host not to be present during the obstacle trails. Even in some international versions, the host does his job from a studio.

The show's format lends itself to it as the anchor has to link the show from the sidelines."

It may sound strange on paper but we'll only know when we see the show which begins February 1 on a primetime slot.

Interestingly, B-Town stars who anchor reality shows on the small screen spent time on location with participants.

The names include Akshay Kumar (first two seasons of Fear Factor Khatron Ke Khiladi in South Africa) and Priyanka Chopra (third season in Brazil).

Bigg Boss has also had its various anchors (Arshad Warsi, Shilpa Shetty, Amitabh Bachchan and Salman Khan) trudge every week to the Bigg Boss house in Lonavla.

Then again, Zor Ka Jhatka believes in being distinct!

Chroma Effect
The actor is filmed against a chroma key background and inserted into the background shot. The principal subject is filmed against a background consisting of a single colour or a relatively narrow range of colors, usually blue or green because these colours are considered to be the furthest away from skin tone. The portions of the video which match the preselected color are replaced by the alternate background video.

The original
Total Wipeout is a British game show hosted by Richard Hammond and Amanda Byram. It first aired in January 2009. Each week, 20 contestants compete in a series of challenges in an attempt to win the cash prize.

These challenges are based in large pools of water or mud and generally involve large assault courses that participants must cross. The show is a licensed version of Wipeout, the show that originated in the United States in 2008.
