During the live launch, presenters said on more than one occasion that Big Brother will be two-faced.

In the lights of the credit crunch and the financial crisis, the house was purposely designed to look cheap.

The first-week task prize was, besides the budget, winning the access to the bathroom, a crowbar and some house tools to open up the crates, and assemble the furniture which was in them.

During Veliki Brat 3, nominations procedure was different from that of the previous years, in that the process was essentially reversed.

There were some variation in the rules: 12 housemates entered the house on launch night (Day 0), on 21 September 2009.

Karlo and Kristina were asked to stay in the secret room, with a mission that could allow them to enter the house.

On 24 October (Day 33), Karlo and Kristina entered the house as temporary housemates.

On 26 October (Day 35), Violeta decided to keep her sister, Kristina, but she was emotionally destroyed.

Out of 18 total housemates, 10 were from Serbia, 4 from Bosnia and Herzegovina, 2 from Montenegro and 2 from the Republic of Macedonia.
