To summarize:
Two teams each from Ecuador, Venezuela, Colombia, Argentina and México, plus one team from Chile.
One team from Ecuador and one team from Colombia confirmed as having been on reality TV before.
Only one female-female team, two male-male teams, and the rest are male-female couples.
No one in the picture looks older. They all seem young.
There are lots of problems with the casting, and many people have commented in the Facebook groups and pages related to TARLA.
It seems the casting process was a farce: there's NO WAY the casting directors read through applications, watched videos, called people back, had interviews and flew everyone into Ecuador in 18 days.
The application form listed all countries in Latin America, yet they selected only the five biggest markets, plus Ecuador (because of the deal with the local government channel).
I'd love for Brazil to host its own show going forward. The country/market is big enough. If it ran on a non-cable TV channel, it would find an audience, just like Big Brother has become a hit there.
