At a time of economic crisis in Brazil, they are doing it on a strict budget.
But his team are promising a spectacle that will be bigger and better than London 2012, which cost $40m (£31m), and was directed by Danny Boyle.
Mr Abete works for Filmmaster Events, and is answerable to the International Olympic Committee for delivering a show that will be watched by a global audience of around three billion people.
"The budget is completely different. We cannot say the real numbers, firstly because we are not allowed, but secondly because it`s really difficult to know what the real number is.
"It`s much less than London. It`s because in Brazil everyone knows what the situation is, economically and politically. It`s correct to invest money in the opening ceremony, but I think it`s also correct to invest the right money.
"We are completely confident we can create an amazing show, without spending the huge amounts that the previous Olympic ceremonies had."
